[gentoo-dev] python ebuild: use tcltk

["Tod M. Neidt" <tneidt@fidnet.com>]

Hi!

Attached is a modified python ebuild (python-2.0-r4.ebuild) that will
include the tkinter module if USE tcltk is set.  I made three changes.

First, Modules/Setup.in is sed'ed to uncomment the relevant tkinter
lines if USE tcltk is set.

Second, if USE tcltk is set, then idle is also installed in
/usr/lib/python2.0/tools with a symlink of idle.py into /usr/bin

Third, the Makefile that is installed in /usr/lib/python2.0/config is
sed'ed to put the value of CFLAGS from /etc/make.conf into the OPT
variable. This appears to be the Makefile that the setup.py  from
distutils calls when building and installing the python module
extensions for any modules installed later.  Note: there is probably a
better way to do it such as putting OPT=$CFLAGS instead of the actual
value.

Constructive criticism is appreciated.
