[CIG-LONG] Recommended Petsc version with Gale

[Dennis Harry]

I just (today) successfully did an install of GALE 1.4.1 with all 
supporting packages on a new Fedora 2.6 machine.  As Walter mentions, I 
found petsc 2.3.2 to work.  But I ran into one quirk.  I opted to let 
petsc install blas-linpack and mpi when I configured it (as I said, this 
is a brand new Fedora machine so it's pretty empty in regards to 
packages).  Things looked good, but petsc stalled in "make test" - no 
errors, it just stalled after telling me it was running the 1-processor 
test. I ctl-c out of that (after letting it think overnight) and tried 
the Gale install, which complained about not finding mpi libs.  So I 
installed mpi manually following the instructions on their web site 
(which was surprisingly easy).  Then I tried to re-install petsc without 
having it download mpi.  It griped.  So I installed petsc and told it 
(again) to download mpi and blas-lapack.  Success, but it again stalled 
at the "make test". I again ctl-c out of that and did the Gale make and 
all is good. I'm able to run the Gale cookbook tests.

So, it seems that Gale wants mpi pieces that aren't installed when we 
request to include mpi in the petsc installation (or I can't figure out 
how to tell Gale where the pieces are).  Manually installing mpi seems 
to fix Gale's needs, but not petsc (again, maybe I'm not telling petsc 
where the pieces are).  I suspect I have two copies of mpi on my 
machine, one that petsc found in it's install directory and the other in 
/usr/local that Gale found. Anyhow, it works.

Now I'm on to other aggravations.  I can't get paraview to install 
properly.  Ugh. As Rosanne Rosannadana used to say "it's always something".
