wxPoint is defined in wx/gdicmn.h which is currently only indirectly
included in wxproj.cpp. Your wx version is newer than the one we
currently use so I compiled a newer one to check whether something has
changed in this regard. Still works for me, though.

Nevertheless there must be a problem with the include files somewhere.
You can try two things:

 - add an #include <wx/gdicmn.h> to wxproj.cpp to make sure that
   headerfile is included

 - Add a -H to the options of gcc when compiling wxproj.cpp to see which
   headerfiles are actually used.

According to
http://rpms.mandrakeclub.com/rpms/mandrake/9.1/contrib/i586/libwxPythonGTK2.4-devel-2.4.0.6-1mdk.i586.html
this RPM contains all wxGTK headerfiles wx/gdicmn.h so at least gdicmn.h
is not missing.

Seems a bit strange to put those headerfiles in a
libwxPythonGTK2.4-devel RPM isntead of say a libwxGTK-2.4 devel, though.

Some of these RPMs have slightly different versions (e.g. 2.4.1.2 vs.
2.4.2) this may cause segfaults when trying to display shapefiles as
experience has unfortunately shown as there seem to be some binary
incompatibilities in some cases.
