[gentoo-science] sci-physics/lammps: question on proper integration of mpi

[Nicolas Bock]

Hi,

I recently added a lammps ebuild to the science overlay. It so far only
builds the serial version, and has very limited support for build time
options. I now added the mpi use flag and changed the ebuild so that it
builds the mpi version. I have attached a patch against master that does
this. I would like to get some feedback on those changes. Are they
acceptable in this form? What should I have done differently? How would I
go about writing an ebuild that builds both, the serial _and_ the mpi
version in case the mpi use flag is set?

Thanks already,

nick
