Cannot emerge ddcontrol with gtk useflag if x11-proto/glproto or x11-proto/dri2proto are not installed. I'd expect that "emerge app-misc/ddcontrol" would emerge the aforementioned two packages, so I think there is a missing dependecy. This is the interesting part of output of ./configure ; checking for gtk+>=2.4 and gthread>=2.4... Package glproto was not found in the pkg-config search path. Perhaps you should add the directory containing `glproto.pc' to the PKG_CONFIG_PATH environment variable Package 'glproto', required by 'gl', not found

not a bug in ddccontrol. ddccontrol only needs gtk+/gthread. those packages need other things, but those are the problem of those other packages. in this case, it seems like it's a matter of: ddccontrol needs gtk+ gtk+ needs cairo cairo needs gl gl needs glproto whether this is user error or something else, that's prob for the gnome/cairo guys to decide
$ equery depgraph --depth=3 =app-misc/ddccontrol-0.4.2 | grep glproto [ 3] x11-proto/glproto-1.4.14-r1 $ equery depgraph --depth=3 =app-misc/ddccontrol-0.4.2 | grep dri2proto [ 3] x11-proto/dri2proto-2.6 glproto and dri2proto are correctly present as indirect (depth 3) dependencies of ddccontrol; uninstalling them and then trying to install ddccontrol is a user mistake. To ensure that none of the indirect dependencies of a package that you are building are missing, it is recommended that you use "emerge --deep" instead of just "emerge" (see man emerge for more information). Using --deep is especially important if you have been cleaning up your system by manually unmerging packages that you might have thought were unneeded.
