I have that on my system too, and I don't use Ruby. Presumably Apple  
provided it with Mac OS X.

You should not have needed to delete part of Mac OS X... Or, where

What is your PATH variable set to? Does it list /opt/local/bin first,  
before /usr/bin? If not, that could have been the problem...
