Hey everyone...

I'm using Linux with Fedora Core 2.  I decided last night I want to try
and install ruby and rails.  Ruby installed very easily, it was a lot
less painless than I thought.  Next I needed to install Gems, upon
attempting to install Gems I realized I also don't have zlib-0.6.0.  I
followed directions (
http://wiki.rubyonrails.com/rails/pages/RailsOnFedora) and used "sudo
yum install zlib-devel".  This installation was successful.

After thinking I had zlib installed I decided to try and install
Gems...packages all extract correctly, but installing I run into these
snags:
------
As of RubyGems 0.8.0, library stubs are no longer needed.
Searching $LOAD_PATH for stubs to optionally delete (may take a
while)...
...done.
No library stubs found.

/root/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in
`require__': no such file to load -- zlib (LoadError)
        from
/root/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in `require'
        from /root/lib/ruby/site_ruby/1.8/rubygems/package.rb:9
        from

Any ideas what my problem can be?  I thought this Rails installation was
going to be easy but now that I'm about 5 hours deep I am rethinking
that...Any help you can give me would be much appreciated.

Thanks a lot.

After you installed zlib library, you need to recompile Ruby. zlib
extension
is missing.
