The wx application now compiles and is usable with the
unstable development branch of wxWidgets-2.9. Some
functions are currently not available in wxWidgets-2.9
and their erlang counterparts are marked as deprecated.
They will generate an error if called when linked against
wxWidgets-2.9 libraries. This means that wx can now be
built on 64bit MacOsX, but keep in mind that
wxWidgets-2.9 is still a development branch and needs (a
lot) more work before it becomes stable.</p>
