Hi Jason,

Glad you're looking into using mesa.   Sorry that the initial build  
It seems that getting everything setup right the first time is a  
for everyone.

First question: which gfortran?  If you don't have a recent version,
that could be a problem.  I get binaries for the mac from this site:

Second question: which mesa?  what svn version number?
The number of the most recent "approved" version can be found here:

Third: what did you do, exactly?

The installation dance goes like this:
	cd mesa

You do clean and install from the top-level mesa directory.

In your case, things are probably fine for all of those items --
so let's dig into the details.   The checks are done for each
module by doing 'ndiff' of an expected output versus the
actual output.  The expected is in 'test_output'; the actual
is in "tmp.txt" -- all of this is in the module test directory of  

TEST FAILED -- compare test_output to tmp.txt

So, what do you find when you look at those files?
In particular, what's in tmp.txt?  That might give a clue
about what's wrong.

Let me know what you find.....
