[ncl-install] ncl 6.4 on osx 10.11.6

[Denise Worthen - NOAA Affiliate]

I've been running 6.3 w/o any problems. I wanted to install 6.4 because of
the ability to add triangle ends to the label bars. I get an error about
libfontconfig version. I've googled around and see that this did seem to be
an issue previously.

I downloaded this version:

ncl_ncarg-6.4.0-MacOS_10.11_64bit_nodap_gnu540.tar.gz

uname -a
Darwin Tobys-MacBook-Pro.local 15.6.0 Darwin Kernel Version 15.6.0: Fri Feb
17 10:21:18 PST 2017; root:xnu-3248.60.11.4.1~1/RELEASE_X86_64 x86_64

​I have 5.4 gfortran/gcc compilers installed in /opt/ports/bin which is
first in my PATH. The which command gives the default /usr/local/
locations. I've attached the output from the set of commands at the bottom
of the MacOSX install page.

Any help would be appreciated.
