Hallo Benny!

 BP> gentoo have python installed both python2 and python3, i dont
 BP> know why :)

Firefox and the like.  Also I believe there are some specific python3 apps used
for development tools not too unlike cmake.  Everything else, such as mesalibs,
still require python2 and thus the additional bloat; both python2 and python3.

 BP> is your plan to make portage in bash ?

No.  Basically what little I have is for keeping track of what to remove if and
when I uninstall a package mostly to facillitate upgrading.  In the case of
glibc it is better to start from scratch and rebuild the entire system which of
this writing consists of exactly 167 packages, including python2 which is
needed by glib which is a dependency for mc.  If I got rid of mc I could
probably get rid of python2 despite a few packages (alsa for example) whining
about the lack of python2 but not failing to build and/or work without it. 
However I find mc handy to have every now and then, such as for browsing
tarballs, so I put up with python2 in order to develop the few utilities that
require it to be available.  Same with perl which even glibc requires to be
available when building despite the fact it adds too much bloat for what little
actual use I personally have for it.

Het leven is goed,
Maurice
