nautilus2 build/install failure - part 2

[J. W. Ballantine]

During the install of nautilus2, in the install-data-hook in the
data sub directory, the install fails with :
  gmake  install-data-hook
  gmake[4]: Entering directory `/usr/ports/x11-fm/nautilus2/work/nautilus-2.13.
3/data'
  no "/usr/X11R6/share/mime"
  no: not found

When I look at the Makefile the install-data-hook is:
 ${UPDATE_MIME_DATABASE} "${DESTDIR}${prefix}/share/mime"
and UPDATE_MIME_DATABASE is set to "no".

Since no is not a unix command, what should I have set when I build this port
to get something other than no for the UPDATE_MIME_DATABASE var.

Thanks
