#    module add darwin
#    module add mitgcm
#
#  (tested with darwin/20090605 mitgcm/20090605, i.e.,
#  intel/10.0.025 mx/1.0 netcdf/3.6.2/intel-10.0.025 mpich-mx/1.2.7..7/intel-10.0.025)
#
#  These modules set FFLAGS, CFLAGS and CPPFLAGS for mpich and netcdf.
#
#  The SGE -V option for exporting environment variables may also be
#  helpful if you encounter missing-library problems.  Or,
#  alternatively, one may choose to link with one of the intel
#  "-static" or "-i-static" flags.
