My old config: Python 2.6(eselected), 2.7, 3.1 emerge & eselect of Python 3.2, I still 2.6 to be used for 2.x. Following emerge advice I run python-updater. 2.6 PYTHON_TARGET flag was missing for some packages in emerge info, so I manually added them (why shoul I when eselect was used?). After remerge proceeds I got bunch of messages: * It seems that you need to set USE_PYTHON to make sure that legacy * packages will be built with respect to PYTHON_TARGETS correctly: * * USE_PYTHON='2.6 2.7 3.2' * * Please note that after changing the USE_PYTHON variable, you may need * to run 'python-updater' to rebuild affected packages. for setuptools, java-config, argparse. USE_PYTHON should be put into make.conf? If yes, why not use eselect? Is there some documentation for all this PYTHON_TARGETS/USE_PYTHON stuff? Reproducible: Always

If yes, why not use eselect? Is > there some documentation for all this PYTHON_TARGETS/USE_PYTHON stuff? make.conf, yes. eselect can't be used in your case because it only allows you to select one python2 & python3 version; if you want to use 2.6+2.7+3.2, you need to set them all by hand. If you don't want python2.7, you should set proper PYTHON_TARGETS without it. The relevant documentation is the User's Guide [1]. [1]:http://www.gentoo.org/proj/en/Python/python-r1/user-guide.xml
