Both dev-libs/boehm-gc-6.3-r1 and media-gfx/graphviz-1.12-r1 want to install /usr/share/man/man1/gc.1.gz, as detected by emerge with the feature collision-protect. Reproducible: Always Steps to Reproduce:
The boehm-gc man page describes a library, so it should be .3 I reported this to the devloper about a year ago so it should be fixed upstream by now.
It is fixed since boehm-gc-6.4
Since this seems to be a problem on boehm-gc's side, reassigning it to its maintainer.
