Can you provide some more system details, like OS?

In general, we do expect some minor differences in the test results when
compiled on different machines or different compilers than the one where the
standard results were produced, especially if OpenMP is involved.  What do
you mean by more serious differences?

Also, we do have some reports that gfortran 4.5.0 is problematic.  On the
Mac, 4.5.1 should work.  On linux, I'm pretty sure that 4.4.4 works but I
have no information about 4.5.*.  If you have access to ifort, you are
encouraged to use it as it (at least version 11) has no known problems with
the current MESA.

No language evangelism here so far.  The MESA Council is happy to look at
anything that can broaden or improve the experience.  All of the things you
mentioned sound great!
