The missing groff check was found on my Linux box, and on both my OSX and
Linux box I use a package/build manager (nix [0]) that, among other
things, performs each build essentially in a chroot containing only the
dependencies you explicitly tell it to contain. Usually when adding a new
package I add dependencies one by one as different configure steps fail,
and these two just failed later.
