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'. ]

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).

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
