The ebuild of games-board/xskat uses xmkmf and imake for building but doesn't have them in DEPEND (assuming modular X). IMHO, the proper dependencies would be the following: RDEPEND="|| ( x11-libs/libX11 virtual/x11 )" DEPEND="${RDEPEND} || ( ( app-text/rman x11-misc/gccmakedep x11-misc/imake x11-proto/xproto ) virtual/x11 )"
