OpenMPI has a serious bug that prevents me from using it atm (it's
fixed upstream). LAM (and I assume also OpenMPI) has a big advantage
when it comes to debugging... you can start any command using mpirun,
so you can also run "mpirun valgrind ./executable" for example.

Actually I don't care which MPI-documentation I have installed. As
this problem persists I install lam4-doc. But the recommendation of
mpich2-doc results in the removal of lam4-dev as the prefered solution
of apt. This behaviour is imho strange for the average user.


PS: Wouldn't a NMU of lam be a better solution to the manpage problem
    than this conflict?
