Since Ruby follows largely the same rules as FreeBSD about where stuff
goes, this isn't actually too difficult to do. You need to find and delete
any binaries/executables that were installed - ruby itself, irb, erb,
ri, rdoc, etc. Then, delete /usr/local/lib/ruby/1.9, locate and remove
man pages etc:

 # find /usr/local/man -name 'ruby*' -ok rm {} \;

should do the trick.

You may have some include files as well, which can probably be found in
/usr/local/include.

When you install the correct version, use the ports - that way, if you
ever need to remove it again, your ports management utility will be able
to find and clear everything for you.
