Bugzilla Bug 167883

* checking 1276 files for package collisions
existing file /usr/share/man/man1/etags.1.bz2 is not owned by this package
existing file /usr/share/man/man1/ctags.1.bz2 is not owned by this package
1000 files checked ...
existing file /usr/bin/b2m is not owned by this package
existing file /usr/bin/ctags is not owned by this package
existing file /usr/bin/etags is not owned by this package
existing file /usr/bin/rcs-checkin is not owned by this package

"equery b" didn't find any owner for any of the files however, so I forced
installation with:

FEATURES="-collision-protect" emerge -av xemacs

ok I now also got it for sys-apps/pciutils-2.2.4-r2:

* checking 18 files for package collisions
existing file /usr/share/misc/pci.ids is not owned by this package

Again not owned by any package. Not sure what is going on

We can't fix collisions with unknown stuff. As for pciutils, just delete the
file and re-emerge.

This is a collision between emacs{,-cvs} and xemacs. The files (these are
really symlinks) are not owned by the emacs package because they are created in
pkg_postinst.

For emacs{,-cvs} the problem will be solved by an eselect module. It is already
available for testing in the emacs overlay.

XEmacs is already using symlinks for the files in /usr/bin (this is bug
#62991). However, the ctags.1 and etags.1 man pages are still installed as
plain files and should probably be changed to symlinks, too.

Please reopen.

Yes, I think we are now able to fix it.

As discussed with Hans de Graaff, I have committed xemacs-21.4.20-r3 which
calls the emacs eselect module in its pkg_postinst and pkg_postrm functions.
This should address the file collision issues.
