Hmmm, interesting.
I had four docbook things already installed:
  docbook-sgml-4.5_1
  docbook-xml-5.0_2
  docbook-sxl-1.76.1_2
  sdocbook-xml-1.1_1,2

I copied a docbook.xsl into /usr/local/share/xmlto
and tried rebuilding devel/dbus but that didn't change anything.

I then reinstalled the four docbook ports listed above and somehow that
fixed it.
The "only" thing different is docbook.xsl was still in
/usr/local/share/xmlto when I rebuilt.

Anyway, thanks.
