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:
Add direct dependency on libiconv.

With default options, this was pulled in via arts->glib2->libiconv,
so no (and especially no recursive) PKGREVISION bump.

Log message:
Exclude Darwin also in buildlink3.mk

Log message:
Update to 1.2.11:

SDL 1.2.11 is a minor bug fix release.

Unix Notes

Dynamic X11 loading is only enabled with gcc 4 supporting -fvisibility=hidden.  \ 
This fixes crashes related to symbol collisions, and allows building on Solaris \ 
and IRIX.

Fixed building SDL with Xinerama disabled.

Fixed DRI OpenGL library loading, using RTLD_GLOBAL in dlopen().

Added pkgconfig configuration support.

Mac OS X Notes

The Quartz video driver supports 32x32 cursors on Mac OS X 10.3 and above.

Log message:
Remove unneeded chunk, noted by markd.

Log message:
MacOSX also provides GL, so avoid depending on GL onthat platform

Log message:
Revert previous because it changed the libraries libSDL was linked to.
Instead, try to dlopen the libraries straight from the directories they
are in.

Bump PKGREVISION to 2.

Requested and reviewed by wiz@.

Log message:
Disable dlopen for libraries and instead link the SDL library to them
directly.  This didn't work because dlopen uses the rpath of the foremost
binary (not libSDL's one); therefore, some libraries could not be found.

For example, qemu was not working at all because it only has PREFIX in
its rpath, not X11PREFIX, and so libSDL could not load libX11 resulting
in a very strange error message.

There seem to be other problems such as the aalib video output crashing
or the wscons output not working, but these aren't very important (maybe
the problems have already gone away with this fix, I don't know).  Anyway,
I think the former is fixed in 1.2.11.

Bump PKGREVISION to 1.

Log message:
Make aalib an option, enabled by default
