Check your PATH
Install anything recently that likes to change the path ? (python for
example or other command line tools?)

BTW, Giles, I know you run OS X, so it is probably your path getting
mucked up by either an installation of something, or a software
update of some kind. I've had it happen and seen it on the list at
least once a week lately.
There seem to be two schools of thought out there for setting paths
in OS X, the "python school" and the "ruby school"
basically, one camp likes to use a different dot file in the home
directory and the other camp likes to use another dot file.
In the python world, they seem to want to add a .bash_profile when
installing, rather than checking to see what you are already using.
In the ruby world we tend to use the .bash_login for OS X.
there is also the possibility of a .bashrc
You're better off having only one of those, you'll likely know which
one is the culprit by looking at the mtime (modified time) on the
file in the file system.
open it and your usual path setting dot file, and adjust to fit your
original scheme.

I can only guess that by creating another dot file, they're trying
not to gum up your existing path, but that could be respected by
commenting it out and appending the file with the new path...

When adjusting the dot files and paths, don't forget to comment them
so you know why and what you changed later!

and in my world they are all them same - you just have to guard them
in order to make them re-entrant. safest thing on osx - the dotfile
semantics there are weird...

It's true, I did mess around with my PATH the other day. I was going
nuts trying to install lejos, which is the Java API and VM for Lego
Mindstorms robots. But the weird thing is that I reverted the changes
in my .profile (to add to the list of dot files) and gem's still
invisible to bash.

I think something went wrong with gem itself. I'm expecting it to be
in /opt/local/bin/gem, but it isn't there. The output from locate gem
is absurd overkill, but maybe a long-running find.

Check your PATH, `gem` doesn't delete itself.

An uninstaller for RubyGems? Yes, but I have no interest in writing
it now.

no i meant on option to gem that would delete itself. or maybe a
feature that just does it randomly?
