I shoudl mention here that if you need "gcc" to be a different version in
order to build something outside of MacPorts, you should use "port select":

    $ port select --list gcc
    (list of available selections here)
    $ sudo port select --set gcc mp-gcc49 # (or other version as available
from above list)
