gentoo軟件安裝錯誤Active gcc profile is invalid解決辦法
版本：Gentoo Base System release 2.1
時間：2013-3-21
GCC : gcc version 4.6.3 (Gentoo 4.6.3 p1.11, pie-0.5.2)
在用install-x86-minimal-20121213安裝完之後，將系統升級至最新後，再安裝一些軟件，會出現下面大概類似的錯誤

解決方法：
gentoo ~ # gcc-config -l
* gcc-config: Active gcc profile is invalid!
[1] i686-pc-linux-gnu-4.6.3
gentoo ~ # gcc-config -c
* gcc-config: Active gcc profile is invalid!
[1] i686-pc-linux-gnu-4.6.3
gentoo ~ # gcc-config i686-pc-linux-gnu-4.6.3
* Switching native-compiler to i686-pc-linux-gnu-4.6.3 ...
>>> Regenerating /etc/ld.so.cache... [ ok ]
* If you intend to use the gcc from the new profile in an already
* running shell, please remember to do:
* . /etc/profile
gentoo ~ # . /etc/profile
