kdrive's description says, "Xfree86: famous and free X server. Tiny version (KDrive)". Therefore, it should provide virtual/x11 just like Xorg does. However, this is not specified in the ebuild.

The virtual is only provided by things that allow other programs to compile against needed X libraries and headers. Otherwise it would be pretty pointless, because you'd install X and still everything requiring X to build would break.
