>>> Failed to install sys-devel/gcc-config-2.3.1, Log file:

 * Messages for package sys-devel/gcc-config-2.3.1:

 * 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 https://bugs.gentoo.org/ unless you report exactly
 * which two packages install the same file(s). See
 * https://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.

This should not have "failed" as no (previous) owners of those files were found.

[Comment 2 Sergei Trofimovich (RETIRED) 2020-08-18 17:57:27 UTC]

It's probably an effect of FEATURES=collision-protect. It makes onowned->owned transition a bit painful. You'll need to remove unowned files manually.
