Hi Daniel,

thanks for the suggestion!

I implemented a patch that sets a variable to the default version used
on the building arch. This can be more easily done and should work for
your case. You would need to do something like this:

include /usr/share/mpi-default-dev/debian_defaults
ifneq (,$(findstring $(ARCH_DEFAULT_MPI_IMPL),openmpi))
...
endif

Would this solve your problem?

I'm also not sure about the path. I put it in /u/s/mpi-default-dev since
this is the package that provides it. /u/s/mpi-default is fine with me
too. Adam, any preferences?

Best regards
Manuel
