  Trouble... I do not think I ever thought of exposing the whole
'overload resolution' infrastructure outside the wxPerl tree.
You might want to avoid it until I figure out how exactly to do it.

  For ovl_const see above. I will remove the requirement for pipe.pl:
it is not intentional.

  The headers of wxTreeListCtrl are wrong. They use WXDLLEXPORT for 
their own classes. You need to replace WXDLLEXPORT with WXDLLEXPORT_TREE
(or something like it) and then define WXDLLEXPORT_TREE to nothing
(because you are not building a DLL that export the wxTreeListCtrl interface).

  Please note that if you distribute wxTreeListCtrl files you need at least
point out it in the module's documentation/copyright section.
