 Full log attached.

 This seems to be due to the recent upgrade of libpng to version 1.5.
 There's a patch at http://www.pkgbuild.com/~ioni/libpng-1.5/pgplot-
 libpng15.patch which should do the trick. I'm not sure what the correct
 attribution for that patch is, though -- it looks like
 http://www.pkgbuild.com/ is associated with Arch Linux, but nobody is
 directly claiming credit.
