hmm -- until today, on my box

$ sudo gem install pg

resulted in 0.8.0 being installed

today, it installed 0.9.0.

try this

in your gems directory, remove the 0.9.0 directory
(on my box this is at /usr/lib/ruby/gems/1.8/gems/pg-0.9.0)

then try the install again

$ sudo gem install pg

Can you post the contents of mkmf.log that are located here: /var/lib/
gems/1.8/gems/pg-0.9.0/ext

Seems that it finds the headers, the pg_config tool, but It cannot
link to it, which may be related to 32/64 bits binaries.

what is this supposed to be?
Click to expand...

Is testing the locations of the libraries:

http://bitbucket.org/ged/ruby-pg/src/tip/ext/extconf.rb#cl-103

If cannot find one, then reports the problem.

I see that postgres was installed using homebrew, which I'm not
familiar with the settings it will use to build stuff.

I would suggest you direct these questions to the developers of pg
gem, as this issue is quite specific of your combination of elements
in your environment.

You can find all the related links here:

http://rubygems.org/gems/pg

Apologizes for not being more helpful.

I am having the exact same problem on a fresh install on Snow Leopard
with Ruby 1.9.1p376 and postgres installed via homebrew. This is the
last entry from mkmf.log
Click to expand...

I assume you're the anonymous creator of this ticket:

http://bitbucket.org/ged/ruby-pg/issue/24/090-gem-fails-to-build

as the description looks the same. If you are, you have the ARCHFLAGS
environment variable set to "-arch i386", which isn't correct for Snow
Leopard. Try either unsetting ARCHFLAGS, in which case the build system
should detect the correct setting, or reset it manually to "-arch x86_64".

If you aren't the creator of that ticket (and you aren't manually
setting your ARCHFLAGS to the incorrect architecture), please file a bug
with the output from 'gem install pg' here:

http://bitbucket.org/ged/ruby-pg/issues/new/

and attach your mkmf.log in its entirety. Thanks!

Doh! Even though the system it completely new, I had copied over my
bash_profile and it was indeed setting ARCHFLAGS to '-arch i386'. Works
perfectly after removing it.

Thanks a lot for the help, much appreciated.

This post was helpful because it helped me to realize that I needed gcc
installed to install the gem

thx
