Ruby searches a default list of directories. You can see
that list by entering this command:

ruby -e 'puts $:.join("\n")'

On my Mandrake system the output looks like this:

/usr/local/lib/ruby/site_ruby/1.8
/usr/local/lib/ruby/site_ruby/1.8/i686-linux
/usr/local/lib/ruby/site_ruby
/usr/local/lib/ruby/1.8
/usr/local/lib/ruby/1.8/i686-linux

The exact list you see depends on how you installed Ruby. If you compiled
from source, it should look pretty much like mine. If you installed from
an .rpm, the prefix is probably '/usr' instead of '/usr/local' (assuming
you took the default).

Look in those directories to make sure everything looks okay. If not, try
to determine what went wrong during the install. Did you get any error
messages? How did you install? From source, or from an rpm?
