Major updateŠ Is ok, I can reinstall if I hosed it all :)
Download gcc-4.8.1.tar.bz2 from gnu and untar into ~/toolchain (no ports patches added to source). Configure as follows (shown below). Make check, make install into /opt/local and it works. The attached threading test program works. The only thing I added that ports didn't is --enable-libstdcxx-threads. 40_ g++-mp-4.8 -v Using built-in specs.
