Hi,
I stupidly unmerged Python and therefore emerge no longer works, I've been googling like mad and have tried a couple of solutions, but neither have worked:
http://www.linuxquestions.org/questions/linux-distributions-5/unmerged-python-in-gentoo-system-224430/
https://forums.gentoo.org/viewtopic-t-5746-highlight-unmerged+python.html
In the second link, it says

You might be able to reinstall Python using this:
Code:
# cd
# tar xzf /usr/portage/distfiles/Python-2.2.1.tgz
# cd Python-2.2.1
# ./configure --with-fpectl --infodir=/usr/share/info/ --mandir=/usr/share/man
# make
# make install prefix=/usr
# rm /usr/bin/python 2>/dev/null
# ln -s /usr/bin/python2 /usr/bin/python


This fails at the make install stage:

Code:
...
Compiling /usr/lib/python2.5/xml/sax/_exceptions.py ...
Compiling /usr/lib/python2.5/xml/sax/expatreader.py ...
Compiling /usr/lib/python2.5/xml/sax/handler.py ...

Compiling /usr/lib/python2.5/xmlrpclib.py ...
Compiling /usr/lib/python2.5/zipfile.py ...
make: *** [libinstall] Error 1


I thought it was about time to ask for some help before I break it any further.
Thanks.

Code:

Have you tried installing and/or compiling Python from an external source?

Try grabbing a python tarball from here and untarring the tarball to /

Sorry for sounding like a complete n00b, but those folders only contain .ebuild files, no tarballs containing the source code. Where can i get these from?

This is for x86. Change to different directory depending on your ARCH.
By the way, these are NOT source codes. These are the ready-to-install binaries.

I think you can just download this python if you are using the x86 arch and then move it to /

then as root
Code:


tar -jxvf foo.bz2



where foo is the package name.

Hope this works for ya.

If it were me:
Code:
tar -xvaf /usr/portage/distfiles/python-2.most.recent.version.tar.gz
cd python-most.recent
./configure
make
make install
emerge -1 python
make uninstall
emerge -1 python
No matter what you do, make sure that when you're done you delete the files you create - having cruft associated with a compiler can be problematic.

Thanks a lot, that worked a treat. All I had to do after the extraction was make a symbolic link from /usr/bin/python to /usr/bin/python2.5.

Thanks for the suggestion. Unfortunately I recently ran an eclean and no longer had the sources.

In some unfortunate irony, I mistakenly removed python as well (trying to fix a broken build in the evening). I followed what you recommended and it worked quite well. I did have to some extra steps, however:

1) The Python source archive, which has a capital P, is a bzip2, not gzip, tar archive.
2) Emerge did not work initially as python was installed into the /usr/local directory. I had to create a symlink in /usr/bin to the newly installed python in /usr/local/bin
3) I did not use the -1 as I do want it added to the world tree
4) There is no make uninstall for Python it seems, I had to remove the files in /usr/local by hand.

At the end I did follow the emerge instructions and ran /usr/sbin/python-updater, though I don't know if that was necessary.

Adam.
