I'm having trouble with porting my scripts. I think the issue is with the
installation of the Traits components but can't get any further:

________________________________________________________________________________
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.

Also, when I try a very basic Traits based UI I get:
