Your diagnosis above related to the $(SWIG) variable is correct.  However,
the problem cannot be caused at all by the absence of the option
--enable-maintainer-mode.  I introduced maintainer-mode in a recent commit
(by adding AM_MAINTAINER_MODE to configure.ac) but for now the only thing
that is done in maintainer mode is the printing of a warning message about
the unavailability of swig.

To sum up: even with option --disable-maintainer-mode (or, equivalently, by
omitting --enable-maintainer-mode), but with --enable-python, the swig
checks are done, and the SWIG variable *must* be AC_SUBSTituted by either
"swig" or "echo swig program not available #".

I think that Joao should, first of all, update his AutoTools to the latest
versions, and then try to reproduce the bug.
