In the former case, no dependency needs to be declared, because that comes with the OS and we don't have a virtual package for it.  For the latter, even though it ships with the OS on current versions, it's good to specify Depends: x11-shlibs and BuildDepends: x11-dev, plus RuntimeDepends: x11 if it displays in X11. (mesa is also a possibility, but I'd recommend not going with that if you don't have to)

SDL-Ball has a very rudimentary build system with no configure script.  The author claims that on linux and Windows systems 'make' is all that's needed.  On OSX, however, the make immediately bombs out:

Hmm....Maybe Macports sets the X11 flags implicitly.

I see a couple options to try here:

1)  Try adding

	SetLDFLAGS: /usr/X11/lib

(and you might also include the stuff from Macports in that).

2)  Patch Makefile to replace '-lGL -lGLU' with '-Wl,-framework,OpenGL'
