[DebianGIS-dev] Bug#510057: Bug#510057: Consider creating "default MPI" version

[Adam C Powell IV]

Dear Francesco,

This patch has been available since early February now, and without it a
number of packages are blocked.  Those include new packages for Salomé
and Code-Aster, a mpi-defaults transition for Octave, and a working
version of med-fichier.  With the freeze coming up soon, it would help a
lot of people to get this done, as these engineering simulation packages
could enter Debian in time for the squeeze release.

Also, mpi-defaults in unstable still uses lam, so the patch is still
current, though it won't be for long.

What more do you need to make this happen?  How can I help?

-Adam
