Installing Gtk-Perl

Speaking of installing Gtk-Perl...

I am having trouble with the Bonobo installation from Gtk-Perl-0.7008.

The usual "perl Makefile.PL; make; make install" doesn't install Bonobo.

When I go into the Bonobo directory, "perl Makefile.PL" shows no errors.
However, "make" does:

[daniel@net104 Bonobo]$ make
make: *** No rule to make target
`/home/daniel/src/cpan/Gtk-Perl-0.7008/Bonobo/orbit.typemap', needed by
`pm_to_blib'.  Stop.

What is this 'orbit.typemap' file?
Does anyone know what this means?

Cheers,
Daniel.
