>Description:
	Whilst the majority of devel/gettext-using ports play with
	USE_GETTEXT, there are a considerable number of other ports in
	the tree that make use of gettext as a build-time-only dependency.

	This patch adds two extra value to USE_GETTEXT:

	build	added to BUILD_DEPENDS
	run	added to RUN_DEPENDS (for completeness sake)

	Similar to the way in which USE_BISON is implemented.

	By migrating _all_ ports that depend on devel/gettext to using
	USE_GETTEXT (and tweaking of portlint et al to make a direct
	Makefile dependency on devel/gettext a hard error), this will
	_substantially_ make life easier in future gettext updates.

>How-To-Repeat:
>Fix:

	http://people.FreeBSD.org/~ade/use_gettext.diff

	(this just adds the logic to bsd.port.mk -- it'll then be necessary
	to go through and tweak ports in the tree, no PORTREVISION bumps
	necessary, since it'll be a no-op)
