Re: Help: errors in running the example "ESMF_regrid_1.ncl"

The problem is that the "ESMF_RegridWeightGen" executable has a shared library dependency called "libgomp.1.dylib" that your system either doesn't have, or can't find.
If you type "libgomp.1.dylib" in the NCL search window, several links to previous ncl-talk questions on this come up. See:

http://www.ncl.ucar.edu/Support/talk_archives/2012/3229.html

I believe the issue is that you either have a gcc that is too old for the version of NCL that you downloaded, or else it was installed in a location that NCL can't find.

You may either need to upgrade your gcc version, or else try building your own version of ESMF_RegridWeightGen, which is not very trivial.
