Mayavi does not yet work with the latest version of VTK (5.10.0). For now, mayavi should mask VTK versions newer than sci-libs/vtk-5.8.0. Reproducible: Always mailing list discussion: https://mail.enthought.com/pipermail/enthought-dev/2012-July/031268.html
Note that the error "TraitError: Cannot set the undefined 'scaled_text' attribute of a 'TextActor' object." is just one symptom when using VTK 5.10 (this has been fixed on github). There are several other things that need to be changed before mayavi works with VTK 5.10, so for now it should use VTK 5.8.
