Fixed in the x11 overlay.
This bug still exist. I've set global python use flag but problem is mesa emerges before libxml2 when doing emerge -uDN world. re-emerging libxml2 with python solves the problem: # USE="python" emerge libxml2 Steps to Reproduce: 1. make.conf -> VIDEO_CARDS="nouveau" USE="python -hal acpi alsa bash-completion bidi consolekit dbus dri firefox fontconfig ftp kde lm_sensors mmx modules mozilla mpi ncurses networkmanager opengl openmp plasma policykit rdesktop readline rss samba semantic-desktop sharedmem smp spell sse sse2 ssl threads truetype udev unicode usb vnc X xml" 2. emerge -uDN world
The dependency is correct. You can verify by building libxml with USE="python" disabled and then re-emerging mesa. Your problem is more likely some issue with the x11 overlay or an incomplete python-updater run after python upgrade.
