[ncl-install] Library Issues While Installing on OS X

[Alexander Schaefer]

Chris, 

The newest gcc/gfortran compilers are in the 5.x range.  I was told that the el capitan release was compiled with gcc/gfortran 5.3.

Try upgrading to those.  I am running 5.3 compilers and it is working swell.

I can get the "ncl" command to return the right information (the version, the copy right, etc.), but once I try a test command like "ng4ex gsun01n -clean," I run into trouble. The terminal returns:
