LoadError while installing RubyGems 0.8.4

[Thursday]

I'm running into an error when installing RubyGems on new Linux box
using Ruby 1.8.2 2005-01-06 snapshot.

I issue 'ruby setup.rb all' as root and get the following error:

[SNIP]

I'm running into an error when installing RubyGems on new Linux box
using Ruby 1.8.2 2005-01-06 snapshot.

I issue 'ruby setup.rb all' as root and get the following error:

[SNIP]

`require': No such file to load -- rubygems/builder (LoadError)
from /usr/local/lib/ruby/site_ruby/1.8/rubygems.rb:58:in `manage_gems'

The solution was to recompile/reinstall ruby after installing zlibc.
The new linux box was missing zlibc at the time ruby was compiled so
ruby didn't have it.

Since the setup.rb error message didn't indicate zlibc as the problem,
it was a royal pain to track down.
