You can use a command such as `portageq  * owners / ` 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.  *   * Detected file collision(s):  *   *  /usr/share/aclocal/gtk-doc.m4  *   * Searching all installed packages for file collisions...  *   * Press Ctrl-C to Stop  *   * dev-build/gtk-doc-am-1.33.2:0::gentoo  *  /usr/share/aclocal/gtk-doc.m4  *   * Package 'dev-util/gtk-doc-am-1.33.2' NOT merged due to file  * collisions.
