Import gcc46-libs-4.6.4nb4 as lang/gcc46-libs.

The GNU Compiler Collection (GCC) includes front ends for C, C++, Objective-C,
Fortran, and Go, as well as libraries for these languages (libstdc++,
libgfortran, ...).

To select gcc46-libs over gcc46, this package's PKGREVISION should start
from 4 (gcc46's 3 + 1).
