Subject: Re: [OMPI users] uninstall

When you built OMPI from hand, you probably configured it with a --
prefix=foo option. Just "rm -rf foo" to uninstall, and then make sure
your PATH and LD_LIBRARY_PATH don't include "foo" any more if you
modified your .login and/or .cshrc files (or whatever you use).
