[installing gcc 5 system-wide through portage]
Now that 5.1 is in Portage (masked), you should keep in mind that emerging it will result in the 5.1 libraries being used, even if you keep 4.9 (or 4.8) as the default compiler.
This is not really guaranteed to work well. AFAIK, the only fully-supported configuration is having the latest emerged gcc version be the default compiler. It might still be best to install 5.1 locally outside of portage if you don't intent to make 5.1 the default system compiler.
