[ncl-install] problems locating libgomp.1.dylib on new install of ncl from binary on MacOS Mojave

[Scott-Fleming, Ian]

Have installed latest version of ncl on an iMac Pro running MacOS Mojave (10.14.6).  When trying to test following the instructions at
https://www.ncl.ucar.edu/Download/install.shtml#DownloadBinary

"You can quickly test if NCL is installed properly by typing:

    ng4ex xy01n -clean

“

I get an error saying it can’t locate libgomp.1.dylib.

I believe I have all appropriate software installed.  From running otool on /opt/local/ncl/bin/ncargpath , it appears to be looking in the wrong place for the dylib.
Xcode and its command line tools are installed.  I have gcc and gfortran installed via MacPorts.

Note:  I have installed ncl in /opt/local/ncl (symlinked to /opt/local/ncl-6.6.2) , rather than in /usr/local .  However, I have NCARG_ROOT pointing to /opt/local/ncl so that *shouldn’t* be an issue.

My diagnostics:   (your requested ones are below as well)

$ ng4ex xy01n -clean
dyld: Library not loaded: /usr/local/lib/libgomp.1.dylib
  Referenced from: /opt/local/ncl/bin/ncargpath
  Reason: image not found

neys:iscottfl:~ $ ls -l $(locate libgomp.1.dylib)
-rwxr-xr-x  1 root  admin  179224 Aug 12 08:43 /opt/local/lib/libgcc/libgomp.1.dylib  <—— actual locate of libgomp.1.dylib

neys:iscottfl:~ $ otool -L /opt/local/ncl/bin/ncargpath
/opt/local/ncl/bin/ncargpath:
/usr/local/lib/libgomp.1.dylib (compatibility version 2.0.0, current version 2.0.0) <—— ncargpath’s expected location.
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1252.200.5)
/usr/local/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0)


Any help would be appreciated.  I suppose if all else fails I can try building ncl rather than using a precompiled binary?

Thanks
