EPD 7.x and most versions of Canopy ship with wxPython 2.8, not 2.9, because of numerous compatibility issues with 2.9. We expect these compatibility issues to be resolved in 2014.
Since wxPython 2.8 does not work at all on 64-bit EPD for OS X, this "computational" version of EPD ships without any version of wxPython.
For now, wxPython 2.9 for Mac OS X (32- or 64-bit) can be downloaded from the EPD repository by registered Enthought users, and used as bleeding-edge, experimental software. It is also included in 64-bit Canopy for OS X.
We recommend that users who do not have a large wx-specific code base use the Qt backend rather than wx. This can be done using either Pyside or PyQt interface package, both available to EPD subscribers. (PyQt is not available for OS X 64-bit.)
Canopy: Import error on Linux, fixed in Canopy 1.0.3
On newer linuxes (Ubuntu 12:04, Fedora 18), import wx fails in Canopy due to compatibility problems with glib bundled with Canopy (as a Qt dependency for RH5) and the system gtk used by wx. This is a known issue with the Canopy Linux beta installers and was fixed in a Canopy 1.0.3.
