How about the autoconf and libtool dependencies? Perhaps they are too
elementary and it is "understood" that they should be present?

Still, it would be good if the ./autogen script gave a nice error
saying "autoconf not present" or "libtool not present" -- but perhaps
these are too small things compared to the purpose of HB...
