Well, FWIW 

a) I think we should at this stage default dbus usage on for generic
Unix and require the use of --disable-dbus if building against a
too-old/missing dbus.

b) I think we should raise the baseline that we build the downloadable
universal version of LibreOffice on from effectively RHEL-4 to at least
RHEL-5.

It'd be nice to have the feature available in the universal builds, and
not just the distro builds, which would mean that gdbus would still be
likely too recent to be universal enough for that build.

I feel this is the best approach. Except that I'll toggle enable-dbus on
by default rather than off when I get the chance. Which would mean that
the rhel-4 based universal-build-generating box would either have to
start using --disable-dbus or get upgraded to something less archaic.
