Comment 32 for bug 184225

Can you check you vnc log and look for this: "Underlying X server release 70200000, The X.Org Foundation" - see what version you see...

Also, verify that the only change you made to the ebuild is the XSERVER_VERSION="1.3.0.0" line, right?

It should then pick up xorg-server-${XSERVER_VERSION}.tar.bz2, and this is the code that the vnc-4.1.2-r4-patches-0.1 file will try to patch. These two seem incompatible entirely... See if, while emerging, you see these exact files being unpacked, etc.
