Log message:
Remove some GNOME1 packages that are unmaintained upstream and/or in
pkgsrc, in preparation for gnome1-libs removal(*).

There was no feedback for keeping these packages after my
HEADS UP mail to pkgsrc-users a week ago.

(*) More to come before that can happen, though.

Log message:
Change the format of BUILDLINK_ORDER to contain depth information as well,
and add a new helper target and script, "show-buildlink3", that outputs
a listing of the buildlink3.mk files included as well as the depth at
which they are included.

For example, "make show-buildlink3" in fonts/Xft2 displays:

	zlib
	fontconfig
	    iconv
	    zlib
	    freetype2
	    expat
	freetype2
	Xrender
	    renderproto

Log message:
Track information in a new variable BUILDLINK_ORDER that informs us
of the order in which buildlink3.mk files are (recursively) included
by a package Makefile.

Log message:
remove extern declaration of static variable
this fixes build problems on darwin

Log message:
Bump BUILDLINK_ABI_DEPENDS.png and PKGREVISION for png-1.2.9nb2 update.

Log message:
Strip ${PKGLOCALEDIR} from PLISTs of packages that already obey
PKGLOCALEDIR and which install their locale files directly under
${PREFIX}/${PKGLOCALEDIR} and sort the PLIST file entries.  From now
on, pkgsrc/mk/plist/plist-locale.awk will automatically handle
transforming the PLIST to refer to the correct locale directory.

Log message:
BUILD_USE_MSGFMT and USE_MSGFMT_PLURALS are obsolete.  Replace with
USE_TOOLS+=msgfmt.

Log message:
Aligned the last line of the buildlink3.mk files with the first line, so
that they look nicer.
