# sudo USE_PYTHON="3.1" emerge -1 dev-python/cython Build log in a second.
Created attachment 253761 [details] cython-0.13 build log
PS: Python 2.6 and 2.7 seem to work fine: # sudo USE_PYTHON="2.6 2.7" emerge -1 dev-python/cython
doesn't block bug 341313 because only ppc64 is left there, and python 3.1 is not even stable on ppc64.
This is a regression in Python. It has been introduced somewhen between 3.1.3_pre20101010 and 3.1.3_pre20101024.
It was rather intentional change: http://svn.python.org/view?view=rev&revision=85392 http://svn.python.org/view?view=rev&revision=85394 http://bugs.python.org/issue10068 http://bugs.python.org/issue7140
I have backported the fix from Cython upstream.
