#  tested on frost, ce107 Aug 4 2005
#  using the following invocation:
#  ../../../tools/genmake2 -of=../../../tools/build_options/linux_ppc64_xlf
#  or with OpenMP:
#  ../../../tools/genmake2 -of=../../../tools/build_options/linux_ppc64_xlf -omp

#  Tested on Big Red, ce107 Aug 30 2007, need to set NETCDF_ROOT to:
#     > export NETCDF_ROOT='/N/soft/linux-sles9-ppc64/netcdf-3.6.1-ibm-64'
#     and at NCAR (on frost ?), need to set NETCDF_ROOT to:
#     > export NETCDF_ROOT='/contrib/fe_tools/xlc64/netcdf-3.6.0-p1'
