[2008/04/30 20:34:22] <evan> thats the installed location
[2008/04/30 20:34:25] <evan> not the current running one
[2008/04/30 20:34:37] <evan> an great example of that is doing ../../blah/bin/ruby


(Note, I don't have any vested interest in this, I am 
merely quoting from the IRC logs... For example, I don't
know why it was important to find the current running
binary.  But I'm not sure how RUBY_ENGINE was supposed
to help in the ../../blah/bin/ruby situation anyway? :)
