wxGTK-2.6.3.2 doesn't install wxrc like wxGTK-2.6.3 does. It's because the former use wxPython-2.6.3.2.tar.gz, instead of wxGTK-2.6.3.tar.gz like the latter. So, I've masked wxGTK-2.6.3.2 to have wxGTK-2.6.3 back (with wxrc), but now I can't install wxPython-2.6.3.2 because it needs it wxGTK-2.6.3.2 unmasked. Something is messed up here... a possible solution would be wxPython-2.6.3.2 doesn't requiring wxGTK-2.6.3.2 (this version of wxWidgets doesn't even exist according to www.wxwidgets.org), using the wxPython-2.6.3.2.tar.gz tarball, and wxGTK using its wxGTK-2.6.3.tar.gz tarball.
