recently found out that portage did not tell me to also emerge libxml2 for getting the compilation of the gnome-panel working. it was not needed for 2.10, but it obviously is for 2.12. i never did a "emerge gnome" or "emerge gnome-light"; i just wanted to use the gnome-panel for xfce. a emerge --pretend gnome/gnome-light didn't tell me to emerge libxml2 too though.
did you have libxml installed already? can you provide an error log? If you already had it installed, this is probably a dupe.
no, i haven't installed libxml before, and unfortunately, i cannot provide an error log. i thought this was not necessary since it was clear to install libxml2 to get it working and this is only a minor bug, isn't it?
I have also incountered this problem, where python would error out "ImportError: No Module named libxml2". Emerging libxml2 would fix the problem, however, it seems the gnome-panel ebuild is missing this dependancy.

I've investigated this issue a bit more. gnome-panel deps on libgnomeui deps on libbonoboui deps on libxml2. Therefore, you should have libxml2 installed. If you did NOT have libxml2 installed, you would have gotten this error: checking for PANEL... configure: error: Package requirements blah blah were not met. This is because it would have tried to get the pkg-config flags, and failed when it got to libgnomeui-2.0 and received the following error: Package libxml-2.0 was not found in the pkg-config search path. Perhaps you should add the directory containing `libxml-2.0.pc' to the PKG_CONFIG_PATH environment variable. Package `libxml-2.0', required by ' libbonoboui', not found and not the ImportError. Therefore, you either: 1) forgot to run python-updater after upgrading python 2) have -python in your use flags. I have committed an updated ebuild to fix the 2nd case only. gnome-panel does not directly depend on libxml2.
