There appears to be version skew between xorg-server and tigervnc in portage - see this link for a patch which restores the correct behavior: http://patchwork.freedesktop.org/patch/7545/ Taking the above patch and creating an updated ebuild with this one line patch is sufficient to correct the problem: --- xorg-server-1.11.2-r2.ebuild 2012-02-22 18:34:25.000000000 +0000 +++ xorg-server-1.11.2-r3.ebuild 2012-02-22 18:35:49.000000000 +0000 @@ -114,6 +114,7 @@ "${FILESDIR}"/${PN}-1.9-nouveau-default.patch "${FILESDIR}"/${PN}-1.11-disable-tests-without-ddx.patch "${FILESDIR}"/${PN}-1.11-pointer-to-int-cast.patch + "${FILESDIR}"/export-GetMaster.patch ) See 335037 for a previous/similar problem with another undefined symbol (AllocDevicePair).

Related threads: http://forums.gentoo.org/viewtopic-p-6933150.html Possibly the same issue affecting tightvnc xorg module. http://forums.gentoo.org/viewtopic-t-908684.html I fixed the problem using the version of the patch from fedora as mentioned in the second thread.
