This is because the location that Debian/Ubuntu's version of rubygems
puts gem executable is not in your path by default, one of many problems
you avoid if you install from source.  I don't recall where Debian dumps
them off the top of my head, but I'll check when I get home. That said,
I _highly_ recommend installing from source instead of using Ubuntu's
version.  You avoid several headaches that way.
