I finally got things work fairly ok:

I edited Makefile.PL with:
   my %DEF_FLAGS = ('GL'        => 0, 
		    'SHAPE'     => 1,
		    'GL_DAMAGE' => 1,
		    'ATC'       => 1
		     );

  ie using GL_DAMAGE instead of GL

  Then:

  make clean
  perl Makefile.PL
  make
  make install

  rebaseall

  perl demos/zinc-demos

  I still get "Use of uninitialized value" errors
  but this seems to be a "common" Tk issue.

  Most of the remaining issues are X-Server related
  eg "GLX not available..." runtime warnings

  I still have 1 annoying issue:
  The following works:
    my $zinc = $mw->Zinc(-width => 500, 
                         -height => 500)->pack();

  The following doesn't work:
    my $zinc = $mw->Scrolled("Zinc",
                             -width => 500,
                             -height => 500,
                             -scrollbars => 'oe')->pack();

  I get:

GLX not available (need at least a 24 bits buffer with stencil)

Seems to be a problem with Tk + Scrolled + Zinc
Other scrolled items (HList, Tree) work fine.

Greetings!
