I don't really know what's going on, but there seem to be two potential 
issues:

* Your wx package has version 0.90 while your wxc package has version 
0.90.0.3. I recommend to use the latest patch level releases of all 
three: wx, wxcore and wxc.

* Your wxWidgets (wxmax) version is reported both as 2.8.12 and 2.9.3.1
