Anthony --

I'm really sorry; we just noticed this message today -- it got lost
in the post-SC recovery/holiday craziness. :-(

Your request is fairly reasonable, but I wouldn't want to make it the
default behavior. Specifically, I can envision some scenarios where
it might be problematic (e.g., heterogeneous situations -- which we
don't yet support, but definitely will someday).

How about this -- an ISV asked me for a similar feature a little
while ago: if mpirun is invoked with an absolute pathname, then use
that base directory (minus the difference from $bindir) as an option
to an implicit --prefix.

(your suggestion may actually be parsed as exactly that, but I wasn't
entirely sure)
