[MacRuby-devel] NSSet and Set broken in MacRuby 0.5 final?

Ah, good to know. But my embedded MacRuby.framework contains all the stuff in Versions/0.5/usr/lib/ruby/1.9.0 including set.rb. Isn't this the whole standard library? 
I am loading my Ruby classes into my Cocoa app by performing a "load" command passed to -[MacRuby evaluateString:]
Might this be a wrong configuration so that MacRuby can't find the embedded standard library?

Cheers
