The default python version on my gentoo is python2, and the default python installed on gentoo has no Tkinter support. After I added the following line to /etc/portage/package.use
dev-lang/python tk
then emerge python, it only shows: [ebuild R ] dev-lang/python-3.1.3-r1 USE="examples gdbm ipv6 ncurses readline sqlite ssl threads tk (wide-unicode) xml -build -doc -wininst" 0 kB
There is no python2!....
How to add Tkinter support to python2?
