More or less; the point is that the Makefile, in order to rebuild
aclocal.m4, wants to use the very version of the aclocal script
provided by the automake tarball you're using; but since you haven't
build that script yet (by running ./configure && make after unpacking
the tarball), the rebuilding of aclocal.m4 fails.

Yes, that was my point (sorry if I didn't manage to make that clear
enough).  As Dave pointed out in a previous mail, you should:

 1.  Unpack tar
 2.  configure
 3.  make  # this will build ./aclocal and ./automake

 Assuming success so far, then proceed to:

 4.  patch tar.m4
 5.  make  # this will use the ./aclocal and ./automake build previously
