Do you have dev-util/gtk-doc or dev-util/gtk-doc-am installed? If yes, what versions of them?
I did not have dev-util/gtk-doc but I did have =dev-util/gtk-doc-am-1.18. The problem is resolved when installing dev-util/gtk-doc too.
Fixed in cvs without a revision bump; patch submitted upstream at https://sourceforge.net/p/cdemu/patches/16/ You should now be able to emerge libmirage-2.0.0 with USE=-doc without needing to have gtk-doc installed. + 30 Jan 2013; Alexandre Rostovtsev <tetromino@gentoo.org> + libmirage-2.0.0.ebuild, +files/libmirage-2.0.0-gtk-doc.patch: + Ensure gtk-doc and gobject-introspection really are optional at build time + (bug #454550, thanks to Cesko Voeten).
