[ncl-install] ncl -V error: dyld: Library not loaded: @rpath/libstdc++.6.dylib

[Little, Matthew Benjamin]

Hello NCL install group,

I am currently trying to install NCL on MacOS.  I initially was using clang, however, I encountered installation problems with clang I switched to gcc.  Nevertheless, the problem that I saw when using clang persists when I issue the command:

$ ncl -V

dyld: Library not loaded: @rpath/libstdc++.6.dylib

  Referenced from: /Users/littlema18/miniconda2/envs/ncl_stable/bin/ncl

  Reason: image not found

Abort trap: 6

This seems to be a common problem from what I can tell, but I feel I have hit a wall with my limited knowledge.  Below are
