Hello, USE="spf" enables SPF support for exim MTA through libspf2. SPF checks in spamassassin however are done through Mail-SPF perl scripts. Having both however is impossible as emerging ends up with a collision information: >>> Failed to install mail-filter/libspf2-1.2.8, Log file: >>> '/var/tmp/portage/mail-filter/libspf2-1.2.8/temp/build.log' * Messages for package mail-filter/libspf2-1.2.8: * 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. * * Detected file collision(s): * * /usr/bin/spfquery * * Searching all installed packages for file collisions... * * Press Ctrl-C to Stop * * dev-perl/Mail-SPF-2.007 * /usr/bin/spfquery * * Package 'mail-filter/libspf2-1.2.8' NOT merged due to file collisions. * If necessary, refer to your elog messages for the whole content of the * above message. This probably refers to all versions, as spfquery is the default comand invoked by these mechanisms. Reproducible: Always Steps to Reproduce: 1. emerge Mail-SPF && emerge libspf2 2. 3.
