If you have the time and the inclination, the best approach would be to
fix the port. You should be very careful with this though, as ports often
involve FreeBSD-specific patches that are applied at various stages during
the build. That is not to say that the lam port requires this, just that
you should examine the package very carefully before getting in too deep.
I would discuss anything that I did not understand directly with the port
maintainers.
My tenency so far has been to take the 'lazy' approach and install from
source. Since my lowly clusters are really just development boxes and
data generators, I justify not maintaining serious software control on
them. They are all built identically so I just dont worry about it.
In either case, you will probably want to remove the lam-mpi installed by
the ports collection before you move ahead with either your own port ora
source install.
I hope this helps!
