The current Version is '=readline-5*'. the only thing, i want to do
next, is to update portage, but portage wants to get a new python and
python a new readline(-6). My Problem is, to install a new readline (-6)
parallel to the old (-5).
Would it help, to change the SLOT Variable in the ebuild files, or
is there any option or Variable to override the slot settings?
