This is probably due to modular xorg, but xvkbd is missing rman as a dependency.
No, it isn't. <snip> RDEPEND="|| ( ( x11-libs/libICE x11-libs/libSM x11-libs/libXtst ) virtual/x11 ) x11-libs/Xaw3d" DEPEND="${RDEPEND} || ( ( x11-misc/imake x11-proto/xproto app-text/rman <==== Here! x11-proto/xextproto ) virtual/x11 )" </snip>
Then how come it never seems to get emerged for me? (Sorry I didn't spot it in the ebuild) Could it be that I have virtual/x11 x11-base/xorg-x11 in my virtuals file? I have it there as it has fixed the issues with xorg 6.9 (and it was in the gentoo weekly to have it in there)
It still does not seem to be pulled as a dependency. Rman is only listed in DEPEND, which is an or to RDEPEND which does not contain rman..
Because you are messing with virtual definitions in /etc/portage/* most likely... Don't EVER do stuff like http://gentoo-wiki.com/HOWTO_Modular_Xorg#.27emerge_-u_world.27_wants_to_install_xorg-x11_6.x_or_virtual.2Fx11
