the vncserver executable is actually a script, so go and edit /usr/bin/vncserver and change the $font_path in there, Default is set up as
$fontPath = "unix/:7100";
but a couple lines down from there is this line:
# $fontPath = "/usr/lib/X11/fonts/misc/,/usr/lib/X11/fonts/75dpi/";
I would try uncommenting this second line and try again. If you get more errors, comment the first line and try again. And if that doesn't work, come back and I'll see if I can help break anything else
