Hi Chris,
Sorry for the delay in response. We are teaching a workshop in Albany this week.
I believe this problem is related to an incompatibility with gcc/gfortran compilers versions.
The NCL binary for MacOS10.6 was built with gcc/gfortran version 4.6.0.
What version do you have on your system?
gcc --version
gfortran --version
--Mary
