(1) I very much thought that I had done graphics with the above build options using png. Without those options R will definitely fail to build on many test platforms, by the way. (2) I don't see why X11 should be necessary to generate png files using R -- the whole point of png's should be to avoid having to use X11. That said, I could be wrong about some of the above. Does R really require X11 as a dependency just to do png graphics? That would suck. OK -- I just retested this on my *linux* install, and indeed, creating png's doesn't work because of no X11. How annoying.
