After I upgraded to Evolution2 the multisync fails to emerge with the following error:

$ emerge module-rebuild
# Populate the database with any packages which currently install drivers into the running kernel.
$ module-rebuild populate

Afterwards I was getting compilation errors on some packages when I try to update the system. I finally managed to salvage the system by following some advice from this discussion post.

In Gentoo, bash-completion is not enabled by default, so for each package compiled with bash-completion support, we need to manually enable it for completion. Here’re the relevant steps and tools to manage bash-completion.

$ emerge bash-completion eselect

Activate bash-completion in bashrc:

$ cd /usr/src; ln -s linux-2.6.12-suspend2-r6/ linux; cd linux
$ make menuconfig

First we try to detect if ethernet is connected before we bring up the interface. We use mii-tool to give us the link status of an interface. If [...]
