[ncl-install] compiler incompatibility??

[Nuss, Wendell (CIV)]

Mary,

Okay it turned out that I had gfortran 4.2.1 installed in /usr/bin using Xcode 4.1 but had to download gfortran 4.6.1 to get the dylib's needed for ncarg. Switched everything over to gfortran 4.6.1 and its happy now.

Thanks for the insights.

Wendell
