I found out what the problem was; the 1.9.* package of Ruby apparently contains a flawed version of RubyGems, with some custom_require.rb removed or something. A manual reinstallation of RubyGems from source fixed everything.

I found and fixed the problem in the meantime;
Apparently, the Ruby package I downloaded lacks one file (custom_require.rb) that makes the whole thing go to hell. I manually reinstalled RubyGems from source, and everything works now.
