Although the configure process associated with installing AmberTools16 on my Mac (OS X 10.11) appears to proceed normally, “make install” eventually terminates with the following message.

running build_ext
building 'pytraj.c_dict' extension
creating build/temp.macosx-10.11-intel-2.7

error: command 'gcc' failed with exit status 1
make[2]: *** [pytraj] Error 1
make[1]: *** [serial] Error 2
make: *** [install] Error 2

My compiler is gcc4.9, and I have python2.7. (The output from the configuration step indicated no issues.) A quick search of the internet indicates that ‘-Wshorten-64-to-32’ is not recognized by gcc. Any suggestions for working around the above error?
