From the ebuild: RDEPEND="|| ( dev-lang/python:2.5 ( dev-lang/python:2.4 dev-python/ctypes ) )" dev-lang/python:2.6 should be added. Note: I did not test whether it works with python-2.6.
Note: I could neither assign this bug to python@gentoo.org nor define a dependency to bug #230205. So, re-assign it please.
pyopengl-3.0.0_beta6 fixes this. Thanks for reporting :)
