In order to run monodoc, libgtkhtml-3 must be installed, however, it is not installed by the ebuild.

This is a known issue that will not be fixed in this fashion. libgtkhtml-3 is a gtk-sharp rdepend, not a monodoc rdepend. We are working with the upstream providers to split gtk-sharp into its component pieces and allow better depends here. Right now, if we were to require all depends to be installed for gtk-sharp to install, emerging gtk-sharp would be similar to emerging the gnome meta package with the amount of extra libraries it could potentially pull in. As of right now, the only fix is to manually emerge it, however, this will be fixed as soon as possible. If you are interested in the specifics, the gtk-sharp/gtk/generated/HTML.cs will show you the P/Invoke call that makes libgtkhtml a rdepend. Thank you very much for your submission.
