Problem installing rubygems

[Andreas Habel]

After downloading the latest sources of ruby-gems 8.10 and

ruby setup.rb all

I ran into errors in post_install.rb. I`ve located the position in code
and reproduced the error in irb:
Any ideas ?
btw. running SuSE 9.3

thanks,
Andreas

def install_sources
$: << "lib"
require 'rubygems'
Gem::manage_gems
Dir.chdir("pkgs/sources") do
load "sources.gemspec"
spec = Gem.sources_spec
gem_file = Gem::Builder.new(spec).build
Gem::Installer.new(gem_file).install(true, Gem.dir, false)
end

I don't think I've seen this issue in SuSE before. This is a common problem
in system that don't bundle zlib with the base ruby installation (or building
from source on systems that don't have the zipping libraries).

You can test this by typing "require 'zlib'" in irb.

See also http://docs.rubygems.org/read/chapter/15#page66 (although the entry
is a bit brief).

Thanks for your help. I build ruby from source and zlib-devel wasn`t
installed because my DVD was only SuSE 9.3 personal ;-(

Now everything works fine!
