Subject: [BUG] RubyGems: "No such file to load -- rubygems/builder"

I added some debug information to the require method as defined
by RubyGems, because I didn't trust a message I got ("No such
file to load -- rubygems/builder").

The problem occurs when require is invoked recursively. In the
situation that a LoadError is thrown some levels deep, the file
it complains about ("rubygems/builder") isn't the file that
raised the exception ("yaml", because it's the first "9"-line).
After installing "libyaml-ruby", I got one step further: "zlib"
is missing", and so on. But in all situations, I got the same
message ("No such file to load -- rubygems/builder").

Looks like a bug...

gegroet,
