[MacRuby-devel] date broken in experimental r2001?

% macirb irb: warn: can't alias exit from irb_exit. irb(main):001:0> require 'date' NoMethodError: undefined method `Rational:' for Date:Class This is with a freshly installed LLVM (r72741, the stable point noted in README.rdoc) and MacRuby r2001. Are other folks seeing this, or is it maybe something about my config? Thanks! -tim
