There is also the whole MPICH/Scalapack interaction...

'apt-cache search mpich' shows quite a few things; and 'apt-cache rdepends'
on some of the shared library packages is inconclusive, but 
	$ apt-cache rdepends mpich-bi
reveals quite a few. Ick.

I think I already did, informally, a few months ago. AFAIK he switch from
being an academic to running a startup, so he kindly reject additional Debian
tasks.

Probably the right thing to do but also a lot of work.  Not sure I can help
with much either -- the packages I care about do run with Open MPI so there
is just not that much of an itch to scratch...
