[ncl-install] Installing NCL on MacOS Catalina

[Marston Ward]

Hi,

I'm trying to install NCL in the old (non-python) way on my new macOS
version 10.15.4. Here are my homebrew specs:

HOMEBREW_VERSION: 2.2.11

I installed ncl via the pre-compiled binaries. I also installed gfortran
via gcc via brew.
But when I try to test ncl, it cannot find the libgomp:

ncargex cpex08 -clean                                                   ─╯
dyld: Library not loaded: /usr/local/lib/libgomp.1.dylib
  Referenced from: /usr/local/ncl-6.6.2/bin/ncargpath
  Reason: image not found
Abort

I'm not sure how to get this library?

Any tips on the this?

Best,
/M
