For some reason xdm is using /usr/local/share/examples/xdm/Xservers
instead of /usr/local/lib/X11/xdm/Xservers.  From some other messages
on the FreeBSD lists, this seems to be a known problem; but so far I
can't see why it's happening to fix it.  

But with the -ignoreABI passed to the X executable in that file,
everything works.  I tried the documented "IgnoreABI" option in the
xorg.conf file, but that didn't seem to have any effect at all.
