= Yeah, you never know if a single program that have USE_GNOME will need
= the latest and greatest. So we're better safe than sorry.

In preparing for that one future possibility we are all suffering
regularly with forced upgrades. Imagine:

	1) install gnome;
	2) a week later - update the ports tree and try to add a
	   gnome-using port (like libwpd);
	3) notice, you have to rebuild your entire gnome.

The sure price of the "safety" of this far exceeds to potential price of
the "sorry". No excuses...

Sure, portupgrade helps, but -- without full rebuilds -- it creates
the shared library mixes, that have their own "sorry" potentials (and
performance costs).

Considering, that most software that has such version demands makes
its own checks in the configure, there is no added safety at all...

= You could add a real LIB_DEPENDS line with >=1.6 to libwpd, right?

Better for those few (if any!) ports, that do need a particular version,
to add their explicit requirements, than for everybody else to do the
opposite.

And no, I can't do it in my port, because bsd.gnome.mk will append its
own (based on USE_GNOME) anyway.
