[ncl-install] ncl_filedump and ncl_convert2nc problem

[Oscar Chimborazo]

Hi Kevin,

I was able to run the tools installing the GCC/GFortran packages you
recommend but not exactly the one that matches the precompiled binary. Let
me tell you. I installed NCL using your precompiled binary, this one:

ncl_ncarg-6.4.0-MacOS_10.12_64bit_gnu530.tar.gz

NCL was not able to run without setting any DYLD_*, and I got the similar
messages when I unset those environment variables. So I installed the
GCC/GFortran packages from the site that you recommend, and now everything
is working fine without setting the environment variables. But I didn't
install gcc-5.3, rather I installed gcc-6.3.  I read about installing the
gcc/gfortran files from that site in the recommendations for installing on
Mac OSX, but I was a little reluctant to install them because I was afraid
of conflicts with my gcc/gfortran installation from MacPorts, and also
because I was surprised and curious that NCL was working except the tools.
Anyway, everything is working fine now. Thank you for your help!

Regards,
Oscar
