Until that time comes, I would like to send an update but I'm having
some problems with it. I need a c++11 lib but I need gcc < 4.9 for the
port to compile on 10.1 (in < 10.x it doesn't build due to the lack of
certain math functions and in > 10.2 it compiles nicely). I've been
playing around with USE_GCC =3D 4.8 to no luck.

How can I specify both, gcc 4.8 specifically and still getting all the
work behing the gcc-c++11-lib ARG?

Thanks in advance.
