Opencv 2.4.13 does not support python 3. PYTHON_COMPAT=( python2_7 )
You used very little words, but I tried to follow your suggestion to add that line to make.conf but it doesn't help. Now I get: "/etc/portage/make.conf", line 383: Invalid token ')' (not '=')
Also: How do I make that change specific to media-libs/opencv? Because make.conf affects all packages.
(In reply to Bodo Thiesen from comment #3) > Also: How do I make that change specific to media-libs/opencv? Because > make.conf affects all packages. Opencv 2.4.13 does not support python 3. There is no support it cannot work with python 3. Please install later versions of opencv if you want python 3 support.

Without -python, everything works now.

Next time put emerge --info and full build.log as is written in the bugzilla. I will look at it. Thanks
