 Should be:
 sudo port -v install vtk5 -carbon +python27 +qt4_mac -tcltk -x11
                           ~~~~~~~
 vtk5 should not be installed with carbon.  With '-carbon -x11', cocoa will
 be used as the backend, and that is what qt4-mac uses. Also +qt4_mac is
 not needed for vtk5, but it doesn't hurt.

 Should be:
 sudo port -v install py27-traitsgui  -wx +qt4
                                 ~~~

 Also, make sure wxwidgets and wxpython are uninstalled or at least
 deactivated and that all your ports are installed either i386 OR x86_64
 (mixing them up or universal builds can cause problems).  I am sorry you
 are having all this trouble.  Mayavi is an unruly beast and I have spent a
 lot of trial and error to get it working over the last few years.
