I think we should be able to come up with a fairly reliable set values
where it's broken.  We can also add a exists(/usr/bin/ctfconvert) to
catch the case were the user caused it to not be there.

It's probably not too bad to add, but I don't think it's changing all
that quickly so as long as people remember to update Makefile.inc1 it
shouldn't too bad.
