Depends upon the procedure followed when it was installed.

If you didn't change --prefix, then my guess is that uninstalling is
going to be tedious. Maybe folks here can offer some tips on what to
look for and delete from your /usr/local.

It's true that there's no "make uninstall" target.

Assuming you're on GNU/Linux:

1. With great care, remove what got installed in /usr/local by the
previous installs.
2. Next time, install in, say, /opt by following the instructions at
http://wiki.rubygarden.org/Ruby/page/show/InstallingRuby under "Custom
Install on GNU/Linux". That way, uninstalling is as easy as "rm -fr
/opt/ruby-1.x.y".
