You've created what in UNIX is called a "symbolic link" from 
/usr/bin/ruby to /usr/local/bin/ruby.  It's a bit hard to explain 
exactly what that means... if you're familiar with Macintosh "Aliases" 
that may be the easiest way to think about it.  You created an alias to 
/usr/local/bin/ruby and put it in /usr/bin.

For more information your best bet may be to "man ln" and read about 
symbolic links.  Alternatively you can search the web and learn as much 
as you like about them :-)
