This took me FOREVER to track down. The problem is that =app-admin/eselect-compiler-2.0.0_rc1-r6 forces gcc to go back to a previous version, namely 3.4.5 even when 4.1.1 has been selected via gcc-config This makes such commands like "emerge -e system" mess up, because half the emerge is with gcc 4.1.1, and the other half is w/3.4.5. This is a serious problem as it has affected subsequent builds and destablized my whole system. I found a thread that discusses the problem: http://forums.gentoo.org/viewtopic-t-471471-highlight-eselectcompiler.html
I should probably explain how I tested this. # gcc-config 9 * Switching native-compiler to x86_64-pc-linux-gnu-4.1.1 ...[ ok ] # gcc-config -l [1] x86_64-pc-linux-gnu-3.4.2 [2] x86_64-pc-linux-gnu-3.4.2-hardened [3] x86_64-pc-linux-gnu-3.4.2-hardenednossp [4] x86_64-pc-linux-gnu-3.4.5 [5] x86_64-pc-linux-gnu-3.4.5-hardened [6] x86_64-pc-linux-gnu-3.4.5-hardenednopie [7] x86_64-pc-linux-gnu-3.4.5-hardenednopiessp [8] x86_64-pc-linux-gnu-3.4.5-hardenednossp [9] x86_64-pc-linux-gnu-4.1.1 * # emerge eselect-compiler . . .

One last note: # eselect compiler list followed by # eselect compiler set ## (where ## equaled the new version) Seems to have fixed this. A subsequent emerge left gcc at 4.1.1. There's nothing about this in the migration guides for gcc that I've seen, assuming this is the desired behavior. W
Did you source /etc/profile after you set the compiler with gcc-config-1.x and before you emerged eselect-compiler. It sets the profile to the compiler being used to emerge it OR nothing if it doens't see a matching profile. That means you were compiling it with 3.4 nad just forgot to . /etc/profile after your gcc-config. Luckily, you don't need to source /etc/profile anymore with eselect-compiler =)
I swear I *did* source /etc/profile . When I did the update, I was on #gentoo-amd64 so I actually typed it twice, once in the terminal and once in irc. I have no idea why it didn't do what it was supposed to... W
Ok, well I'll try to reproduce it, but I did test emerging eselect-compiler with 3.4 and 4.1 installed and with each one as the active compiler. I'll try again, but it's working here...
