| | I admit I'm not so comfortable with these architectures.  Is there any

| 
| There is. We are simply slow in implementing this for all packages.
| 
| [ Long and boring story:  MPICH was never in Debian, LAM deprecated, OpenMPI
|  undermaintained. I adopted it a few years ago; Manuel then took over. Open
|  MPI _upstream_ never had support for certain arches (for performance / ASM
|  use reasons) so we always had these 'holess'. ]

[ Forgot add here that now that we have proper MPICH2 everywhere, it serves
as a fallback where Open MPI --- which AFAIK is still the default where
available --- cannot be used. ]

| The situation is mostly fixed and automatic now.  Instead of depending on
| openmpi, just depend in mpi-default-dev and everything should just work (TM).
| 
| | Could any other package with the same problem serve as an example?
| 
| Here is what my pgapack package does:
| 
|    Build-Depends: debhelper (>= 7.0), mpi-default-dev
| 
| and here is my Rmpi package (which also needs R):
| 
|    Build-Depends: debhelper (>= 7.0.0), cdbs, r-base-dev (>= 2.12.0), mpi-default-dev
| 
| Hope this helps,  Dirk
| 
| | Kind regards
