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. package sys-kernel/gentoo-sources-2.6.31-r6 NOT merged Detected file collision(s): * /usr/src/linux-2.6.31-gentoo-r6/Makefile * /usr/src/linux-2.6.31-gentoo-r6/Kbuild .... gazillion similar ellided * /usr/src/linux-2.6.31-gentoo-r6/include/asm-generic/bitops/lock.h * /usr/src/linux-2.6.31-gentoo-r6/include/asm-generic/bitops/hweight.h * /usr/src/linux-2.6.31-gentoo-r6/include/asm-generic/bitops/non-atomic.h * * Searching all installed packages for file collisions... * * Press Ctrl-C to Stop * * None of the installed packages claim the file(s). * * Package 'sys-kernel/gentoo-sources-2.6.31-r6' NOT merged due to file * collisions.
