Thinking about how you did the --with plf on the freetype2 package, is there also a --without option where you could have something enabled by default but disable it with a build time option?
The reason I was thinking about this is since openssh needs to build openssh-askpass-gnome, it has a whole web of gtk/gnome BuildRequire dependencies, which seems bad for something like openssh, so it would be cool if there was a way you could just disable that package with a build time option. There are lots of other packages that could use this kind of thing too.
