Adam --
Sorry for the delay; I've been on travels for what seems like forever
and have fallen behind on updating the FAQ. I will definitely take
your text and post it soon.
Many thanks! (and keep it coming!)

With no comments in a week, can this go in? Additional optional text

compile programs, you need [libopenmpi-dev], or if you need debugging
symbols, then [libopenmpi-dbg] with debugging symbols.<p> Note: if

\"universe\" packages from Debian unstable at a time set by their
release schedules, a time generally not known to the Debian package
developers, so the quality of the Ubuntu packages is generally not as
good as that of the packages in a Debian release.";
There is an unofficial backport of the 1.2.7-rc1 release for Ubuntu
Hardy Heron which you can get by following the instructions at:

Dirk, any comments?

A number of distributors provide pre-compiled Open-MPI packages, so
one
doesn't need to go to the trouble of compiling it. For example, on
Debian GNU/Linux, Dirk Eddelbuettel has led a packaging effort such
that
"apt-get install libopenmpi-dev openmpi-bin" (or the equivalent
from
aptitude or synaptic) gets everything one needs to compile and
run an
Open-MPI program.
Can someone add this to the FAQ? I'd be glad to contribute a
paragraph,
and update it as needed. (E.g. Debian Lenny will have a working
version
of 1.2.7-rc2, though Ubuntu Hardy universe has AFAIR a buggy
version
of
1.2.5...)

Hi Anughra
Why don't you check the FAQ first:
http://www.open-mpi.org/faq/
It answers may questions and also provides instruction to install
Open-MPI and build MPI applications.
And, yes, Open-MPI works with gcc.
