Ethan Mallove cb7c435a9c Added OMPI_WHICH macro as an alternative to using {{{`which
<prog>`}}} in `configure`. It is preferable to simply using {{{`which
<prog>`}}} because backticks (`) (aka backquotes) invoke a sub-shell
which may source a "noisy" `~/.whatever` file, and we do not want the
error messages to be part of the assignment in {{{foo=`which
<prog>`}}}.

This commit was SVN r16955.
