use gcc-config to select the new gcc as your default compiler env-update source /etc/profile fix_libtool_files.sh 4.3.4 emerge --oneshot libtool then unmerge the old version of gcc revdep-rebuild just to be safe I think that should be all that's needed. I don't think there's any reason to recompile world or anything like this.
