What is USE_PYTHON set for you to ?
linux01 ~ # grep -irs USE_PYTHON /etc/ /etc/make.conf:#USE_PYTHON="2.7 3.1" /etc/make.conf:USE_PYTHON="3.1" linux01 ~ #
You should set: USE_PYTHON="2.7 3.1" dev-libs/libxml2[python] currently does not support Python 3.
I'm going with your suggestion, created /etc/portage/env/dev-libs/dev-libs/libxml2-2.7.8 with USE_PYTHON="2.7 3.1" in it. Works for me till hopefully an upstream will handle python-3.x. Thanks a lot.
correct: /etc/portage/env/dev-libs/libxml2-2.7.8
