Compilation error when launching madgraph

Hi,

The typical way to solve such problem is to run the following command:
xcode-select --install

according to https://stackoverflow.com/questions/19555312/ld-library-not-found-for-lcrt1-10-6-o-after-running-intel-icc-compiler-on-os-m
(it was working for me when moving to Sierra)

Cheers,

Olivier
