Any ideas on what went wrong?

But what I don't get is: I've got gem 1.3.1 and I never had this problem
(same system as you). Perhaps this is a difference between installing
from source and installing from gem.

Hi,

Thanks for the response. My gem questions usually go unanswered. In my
short experience with the gem system, it is a ponderously slow(bulk
updating) broken piece of junk. The gem website here:

http://www.rubygems.org/read/chapter/3#page14

says:

-------
If your RubyGems version is 0.8.5 or later, you can upgrade to the
latest version with:

gem update --system
------

I have ruby-gems 0.9.4 installed, and a couple of weeks ago I tried to
update ruby-gems using that command, and I posted here that I got this
error:


$ sudo gem update --system

ruby 1.8.2 (2004-12-25) [universal-darwin8.0]

I'm no big expert, but at least we have similar systems so a comparison
might be useful in tracking this stuff down. I am using,

ruby 1.8.6 (2008-03-03 patchlevel 114) [powerpc-darwin8.9.0]

My working ruby is in /usr/local.

I've left the built-in ruby in place, so I also have /usr/bin/ruby:

ruby 1.8.2 (2004-12-25) [powerpc-darwin8.0]

But I don't use it.

But I don't think that's the issue. When you get an error message
warning that there is no directory rubygems-update-1.3.1, I tend to
think that this is because you are supposed to have such a directory.
Your quoted material says "Successfully installed
rubygems-update-1.0.0"; but the current version is 1.3.1. So that must
be what rubygems is looking for. I *do* have such a directory:

/usr/local/lib/ruby/gems/1.8/gems/rubygems-update-1.3.1

I think you need that before you can proceed. Of course mine is in a
different place because my ruby is in a different place.

So you could probably get things working by following this procedure
(but use sudo):

$ gem install rubygems-update
$ update_rubygems

However, you don't really need to do that, because, as the Google-found
ruby-forge page I cited says, there was a bug, it has been fixed, and
you can check out working code from the trunk. So your setup.rb approach
should also now work.

What install directions did you use to install 1.8.6?

I've left the built-in ruby in place, so I also have /usr/bin/ruby:

ruby 1.8.2 (2004-12-25) [powerpc-darwin8.0]

But I don't use it.

I think you need that before you can proceed. Of course mine is in a
different place because my ruby is in a different place.

Is that a directory or a file? I looked around on ruby-forge and saw
this:

rubygems-update-1.3.1.gem

and since that matched the file the error message said was missing, I
thought I'd download it and try putting it in the directory indicated in
the error message. When I downloaded that file, it arrived as
rubygems-update-1.3.1.gem.tar and when I tried to untar it:

$ tar -xvf rubygems-update-1.3.1.gem.tar

I got this output:

data.tar.gz
tar: data.tar.gz: implausibly old time stamp 1969-12-31 17:00:00
metadata.gz
tar: metadata.gz: implausibly old time stamp 1969-12-31 17:00:00
data.tar.gz.sig
tar: data.tar.gz.sig: implausibly old time stamp 1969-12-31 17:00:00
metadata.gz.sig
tar: metadata.gz.sig: implausibly old time stamp 1969-12-31 17:00:00

which I thought was an error message, but now I realize that untaring
produced these two files:

metadata.gz
metadata.gz.sig

So you could probably get things working by following this procedure
(but use sudo):

$ gem install rubygems-update
$ update_rubygems

Shouldn't the first command be:

$ gem install -r rubygems-update

-r for remote

And what does the second command do?

However, you don't really need to do that, because, as the Google-found
ruby-forge page I cited says, there was a bug, it has been fixed, and

Do I re-download rubygems-1.3.1?

Thanks.

Ah, I see. That is the way to update for old versions of ruby-gems:

---
Prior to RubyGems 0.8.5
If you current version of RubyGems is prior to version 0.8.5, then use
the following commands:

gem install rubygems-update
update_rubygems
---

vs.

----
Modern Versions of RubyGems
If your RubyGems version is 0.8.5 or later, you can upgrade to the
latest version with:

gem update --system

My gem questions usually go unanswered. In my

It was: on a 512MB system, rubygems would happily eat up all available
memory and go deep into swap.

However 1.3.x seems to have fixed that.

...but as you can see, installing 1.3.x is broken. Sort of a catch-22.

No, your ruby is missing Etc. RubyGems' reporting of this fact is
broken.

Why? Are you suggesting I did it wrong? As far as I know, this is a
completely normal arrangement. m.
