If you don't get this working for some reason, you might think about http://www.tightvnc.com/, which is the VNC setup I'm using now. It even has a Java client that you can use to access your system from a browser via a Java applet. The Xvnc server didn't need an X source tree (comes with a stripped down one) so has less places to go wrong. As I remember it didn't build 100% out of the box, but the changes were minor and doable by someone building his own system.

When the app was made (RealVNC), they may have programmed it against an earlier version of some libraries, which had the symbol defined that is causing the error. Later it was maybe removed, and the program never re-written to take this into account. You see this when functions get ripped out, or re-named, etc.

I'm no XFree86 or RealVNC programmer, I'm just relating what I've seen while building sources.

The error probably doesn't sit within either, but *between* them (eg, their interaction).

HSTH (hope something there helps)
