Ruby gem LoadError - rubygems/defaults/operating_system

Question

I've installed ruby 1.8.6 p368 and gems 1.3.4 as well as required libraries like zlib, ssl or readline on my winxp sp3 box. The problem is, when I now try to use some gem, I get the following error:

Exception `LoadError' at D:/ruby/lib/ruby/site_ruby/1.8/rubygems.rb:1112 - no su
ch file to load -- rubygems/defaults/operating_system
Exception `LoadError' at D:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.
rb:31 - no such file to load -- mysql

Seems like it makes sense to start with fixing the missing "rubygems/defaults/operating_system" file. How can I do that? TIA

PS: gem env is

Were you running using -d? If so, this email reckons that it's displaying exceptions even when they're rescued.
