I think I solved the problem, however I only found a kind of grude
workarround, not a real solution.

The problem seems to be, that petsc is linked to liblam on sparc, and
therefore the additional linkerflad -llam is needed on that arch.  I
have no idea, why this issue han't shown up on armel, mips, mipsel or
s390, the other arches on which petsc uses lam.  My patch adds the
missing flag on sparc.

A nicer fix would be to some detect automatically, if -llam is needed or
not based upon... uh... Don't know what.


That being said, I uploaded the fix to delayed/4.  Please tell me, if I
should delay it longer.


As you can see I also added libmpich2-dev to the build-conflicts.
That's to prevent FTBFS issues as seen while trying to fix the issue in
the porter chroots (see bug log for details).


Best Regards,
  Alexander
