Re: [gentoo-user] python targets problem

[james <garftd@verizon.net>]

Here is some information that may help::

https://wiki.gentoo.org/wiki/Project:Python/Dependencies

It also often helps to just read the ebuilds relevant to the issues
you encounter. For example:

less /usr/portage/dev-python/setuptools/setuptools-36.7.2.ebuild

It's a pita, but as packages are listed in ebuild, check them out
(manually) on your system.


I had some issue with Python of late, and just settled  on the defaults
2.7 && 3.5 and they all cleaned up nicely.
