[ncl-install] ncl -V error: dyld: Library not loaded: @rpath/libcblas.3.dylib

[Vanessa Vincente]

Hello Mae,

Thanks so much for your help. Installing NCL via Anaconda seems to have
resolved my issue with
"dyld: Library not loaded: @rpath/libcblas.3.dylib".  I am able to run the
tests for NCL after installation, and they are working now.

Cheers,
Vanessa
