Newbie install problem

[Terry Carmen]

Could somene take a moment and translate this into English for me?

I'm trying to install NorfelloCMMS, which runs on Ruby/Rails, and the
prerequisites instructions say to run:

gem install rmagick gettext libxml-ruby

Which immediately blows up with the error message below. Any help
would be appreciated.

This is a virgin install of Centos 5.0 with freshly downloaded and
installed ruby (source install from the ruby site).

It seems to be unhappy about "gem_original_require" but I haven't got
a clue where this should be or come from.

Any thoughts?

Thanks!

Terry

rmagick has a ton of prerequisites.
sounds like you need to start by installing zlib

zlib and zlib-devel are installed (from yum). Supposedly ruby has zlib
support built in. Is there anything I need to do to let ruby find
zlib?

Thsnks!

Ruby-zlib should be built into Ruby 1.8

you might want to try building ruby-zlib by hand

wget http://www.blue.sky.or.jp/atelier/ruby/ruby-zlib-0.6.0.tar.gz
tar xvzf ruby-zlib-0.6.0.tar.gz
cd ruby-zlib-0.6.0
ruby extconf.rb && make && make install


then, I would try reinstalling Ruby Gems from source.
