Trying to emerge gimp-2.2.12 with USE="doc" results in a block, 'cause gimp requires gimp-help, but the only version of gimp-help which is in portage is 0.10 and it blocks gimp-2.2.12, cause RDEPEND="!<media-gfx/gimp-2.2.12" The solution is to emerge gimp with USE="-doc" An update of gimp-help, I think, it's needed
No, you need to unmerge the old gimp version first. *** This bug has been marked as a duplicate of 138224 ***
