At the moment, downgrading from cups-1.6 gives you a file collision. Please add the following blocker to all versions of cups-filters: !<net-print/cups-1.6 And the following to all versions of <net-print/cups-1.6: !net-print/cups-filters >>> Installing (1 of 1) net-print/cups-1.5.3 * 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).
