this was why i mentioned ExtUtils::Depends.  it's entire purpose is to 
find include paths and typemaps for other XS modules, and turn that 
information into something that WriteMakefile can use.

in your Makefile.PL, you'd do something like this:

  use ExtUtils::Depends;
  # create an EU::Depends module that depends on Gtk2.
  # since 0.200, it chains dependencies, and will pick up Glib for you.
  my $dep = ExtUtils::Depends->new ('MyModule' => 'Gtk2');
  $dep->add_xs (<*.xs>);  # add your XS files
  # add your pm files; see the docs for PM in MakeMaker for more info.
  # note that $(INST_LIBDIR) is Makefile syntax, not perl.
  $dep->add_pm ('MyModule.pm' => '$(INST_LIBDIR)/MyModule.pm');

  WriteMakefile (
      NAME => 'MyModule',
      VERSION_FROM => 'MyModule.pm',
      $dep->get_makefile_vars,
         # get_makefile_vars replaces all your custom stuff like
         # INC, LIBS, TYPEMAPS, etc
  );


the various Gtk2-Perl modules' Makefile.PLs have more advanced examples.
