some fixes (install on CentOS 6.2)

[mluessi]

Some fixes for problems encountered when installing on CentOS 6.2 (they are not CentOS specific though).

• Masking ">sys-devel/gcc-4.2" masks gcc-4.2.4, so portage pulls in gcc-4.1 in stage4, which fails to build due to "march = native", which is only supported for gcc-4.2 and newer. By masking ">=sys-devel/gcc-4.3", gcc-4.2.4 can be installed.
• stage2-portage failed since the active Python version was not set

Is ">=sys-devel/gcc-4.3" masked to make sure gcc is compatible with the host OS libc (discussed on gentoo-alt a while ago)? If so, I wonder if newer gcc version work with CentOS 6.2, any experience with this?

Thanks for the fixes!

It should work, let me know if you try it out.
