Comment (by jsalort):

 I have the same error message on Intel with Mac OS X 10.6 Snow Leopard. It
 is not a PPC specific issue.
 It works when gcc6 is chosen manually (and after manually downloading the
 distfiles with macports' wget):

 {{{
 sudo port install py27-cryptography configure.compiler=macports-gcc-6
 }}}
