[ncl-install] troubleshoot NCL / NCAR graphics installation (Mac 10.11.6)

[Justin Wettstein]

Dear NCAR-NCL install support,
First, thanks for the development of the NCL and NCAR Graphics toolbox.  I've used both quite a bit in the past and have found them quite useful.  That said, it's been a while and I'm now trying to do a fresh install on a relatively new machine.  I tried to follow the instructions for installing NCL/NCARG from a precompiled binary on a Mac running 10.11 (El Capitan), but am running into some trouble.  
I get the following error when I try to run, even though I believe I have an acceptable version of gfortran installed:
dyld: Library not loaded: /usr/local/lib/libgomp.1.dylib
The most obvious thing is that I don't see libgomp.1.dylib in my /usr/local/lib directory.  What I do see is attached as a screenshot.
Can you help?  I've pasted the output from the troubleshooting commands on the ncl install webpage as a second screenshot.  The "otool" command didn't seem to work, but the others did.
Thanks and best regards,
Justin
