Just in case anyone else runs into it -- xorg on Centos 5 and RealVNC
4.1.2 have conflicting font paths configured. The solution when
running across the error below is to symlink /usr/share/X11 to /usr/
X11R6/lib so RealVNC server (specifically Xvnc) can find fonts under
the correct directory.

# strings /usr/bin/Xvnc | grep X11R6
/usr/X11R6/lib/X11/fonts/misc/,/usr/X11R6/lib/X11/fonts/Speedo/,/usr/
X11R6/lib/X11/fonts/Type1/,/usr/X11R6/lib/X11/fonts/CID/,/usr/X11R6/
lib/X11/fonts/75dpi/,/usr/X11R6/lib/X11/fonts/100dpi/
/usr/X11R6/lib/X11/rgb
/usr/X11R6/lib/X11/xserver/SecurityPolicy
/usr/X11R6/lib/X11/xkb
/usr/X11R6/lib/X11/fonts/encodings/encodings.dir
