>>> Installing (2 of 305) dev-libs/gmp-5.1.3-r1 * Removing /usr/lib/systemd * checking 25 files for package collisions * 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). See * http://wiki.gentoo.org/wiki/Knowledge_Base:Blockers for tips on how to * solve the problem. And once again, please do NOT file a bug report * unless you have completely understood the above message. * * Detected file collision(s): * * /usr/lib32/libgmpxx.so * /usr/lib32/libgmpxx.so.4 * /usr/lib32/libgmp.so * /usr/lib32/libgmp.so.10 * * Searching all installed packages for file collisions... * * Press Ctrl-C to Stop * * app-emulation/emul-linux-x86-baselibs-20130224-r13:0::gentoo * /usr/lib32/libgmp.so * /usr/lib32/libgmp.so.10 * /usr/lib32/libgmpxx.so * /usr/lib32/libgmpxx.so.4
I think I resolved this with some blockers and a revbump on emul-linux-x86-baselibs.
