[mesa-users] Building and running MESA with MacPorts instead of the MESASDK

[Robert FARMER]

Hi
Regarding issue 2) you don't need to worry about those just make sure to
set $MESA_ROOT and $OMP_NUM_THREADS.

Have you gotten mesa to compile with gfortran4.7 and ran the test_suite (go
to star/test_suite and run ./each_test_run_and_diff)? It would be
interesting to see if it passes, as with the sdk+the bundled crlibm we get
bit-for-bit identical results across linux+mac which you may lose using an
older compiler.
