I've never experienced this phenomenon prior to gentoo-sources-2.6.31.-r6. I've always emerged gentoo-sources and they peacefully sat there and waited until I built the corresponding kernel later when I felt like it - if ever. With 2.6.31-r6, however, the emerge fails and consequently screws up 'emerge world' attempts. PITA.


Any recommended workarounds or fixes?

I've pieced the following together from the console and elogv:


ERROR: preinst
This package will overwrite one or more files that may belong to other
packages (see list below). You can use a command such as `portageq
owners / <filename>` to identify the installed package that owns a*****************************

file. If portageq reports that only one package owns a file then do
NOT file a bug report. A bug report is only useful if it identifies at
least two or more packages that are known to install the same file(s).
If a collision occurs and you can not explain where the file came from

then you should simply ignore the collision since there is not enough
information to determine if a real problem exists. Please do NOT file
a bug report at http://bugs.gentoo.org unless you report exactly which

two packages install the same file(s). Once again, please do NOT file
a bug report unless you have completely understood the above message.

*** SNIP ***

So, please check where these files came from by

qfile /usr/src/linux-2.6.31-gentoo-r6/Makefile

Have you installed this kernel 'by hand' i.e. outside of portage?

Check by uname -a if you are not currently running linux-2.6.31-r6

If not, it's safe to rm -rf /usr/src/linux-2.6.31-gentoo-r6
and emerge it again.

Helmut.
