You seem to be suggesting what he *should have done*
The point is, he has already installed multiple (at least 3.0.1 and 2.6.2)
vanilla ("fresh" from http://www.python.org/download/releases/)
python versions manually (with
./configure -with-fpectl -infodir=/usr/share/info/ -mandir=/usr/share/man
make
make install prefix=/usr
)
and then he tried emerge -va python
He followed instructions from this damn blog
http://blogs.pwmn.net/korkakak/2008/06/04/gentoo-i-unmerged-python-now-what
I fear that his system is now a mess, with remains of multiple python versions.
I suggested a idea for how to clean it up (read the quoted text above,
starting with "One idea:")
Anyway, some conclusions:
- The blog solution seems to be a quite bad one, for multiple reasons.
- A better and easier solution would be to install a binary package from
tinderbox. I think he wouldn't even have to extract the tarball manually
with tar; he can use qmerge from portage-utils (written in C AFAIK); I'm
not sure, haven't used qmerge so far
