No, this comment was about the process of building, not about the
PetSc library being an "alternatives". I probably didn't make myself
very clear.


In Debian, we only have a Build-Depends: mechanism where we got to install 
both (mpich and lam), or have a separate source tar.gz's (for building against mpich
and lam).

mpich and lam are alternatives, and which can be used to build 
the two versions, and it should work fine with autobuild machines too.
(it won't work under fakeroot, I believe).

The resulting binary, AFAIK are incompatible.
