Make sure that you have either the TraitsBackendWx or the TraitsBackendQt
projects installed. If you installed Mayavi with easy_install, try easy_install
<pkg_name>. easy_install Mayavi[app] will also work.
If you performed a source checkout, be sure to run 'python setup.py install'
in Traits, TraitsGUI, and the Traits backend of your choice.
Also make sure that either wxPython or PyQT is installed.
