if openmpi is installed on sparc, it takes priority over lam ! (it has priority 40 and lam 30)
-I/usr/lib/openmpi/include -I/usr/lib/openmpi/include/openmpi -pthread
-pthread -L/usr/lib/openmpi/lib -lmpi_cxx -lmpi -lopen-rte -lopen-pal -ldl -Wl,--export-dynamic -lnsl -lutil -lm -ldl
so even though mpi-default-dev point to lam, if openmpi gets also installed it is in practice the default implementation
on sparc !
To my opinion this is a bug in the mpi system. Adam ? Others ?
There are 3 choices for the alternative mpi (providing /usr/include/mpi).
Selection Path Priority Status
* 0 /usr/lib/openmpi/include 40 auto mode
1 /usr/include/lam 30 manual mode
2 /usr/lib/mpich/include 10 manual mode
3 /usr/lib/openmpi/include 40 manual mode

I tried, without success so far, to help cmake(FindMPI.cmake) find the proper mpi implementation.
It still finds openmpi which breaks linkage with boost::mpi

mpi-default-dev and you should have a consistent MPI implementation
That said, the LAM HDF5 implementation seems to be missing a couple of
libraries, such that for example PETSc doesn't build on architectures
where LAM is the default. I disabled PETSc HDF5 support on those
arches, but haven't investigated further.
