[AMBER] problem installing AmberTools16 pytraj on Mac

Hi all,

I just tried to install AmberTools16 on a new Mac Book pro, running OS X El
Capitan (10.11.4).

I've installed and selected gcc4.9 (and also installed flex, py27-numpy &
py27-matplotlib) through MacPorts.

All is well (i.e. most things are compiled) until I get to pytraj, where
"make install" eventually fails with the following:
gcc: error: unrecognized command line option '-Wshorten-64-to-32'

At this point, I don't yet need pytraj, but it would be nice to have a
complete install.
Any insight in how to fix this would be welcome.


More detail:
