I started with a google on "OSX   site:vtk.org python" and started looking for clues.

If you are a Mac OS X user, we strongly recommend you download your own Tcl/Tk distribution and compile it to run in X11 mode (check "Configuring and Running X11 Applications on Mac OS X" for more information about X11). The default Tcl/Tk was built to run in Aqua/Carbon mode, and is not behaving properly.

Here are a couple references that may help in building vtk:

    http://www.vtk.org/pipermail/vtkusers/2003-May/067248.html

The referenced instructions are a couple years old.

Buried at the end is a quote that may provide a clue:
> Some truly impressive work with VTK is being carried out in medical
> research. Yves Starreveld, the key Mac OS X developer for VTK, and the
> person to whom I owe a great deal in helping me out, has his Web site at
> www.atamai.com. At Starreveld's site computer science meets brain surgery.
> Pretty cool! Sebastian Barre has another interesting site using VTK for
> biomedical engineering.    

According to http://www.atamai.com, the email addres of Yves is ystarrev@atamai.com

I've located some issue tracker reports on building Enthought on OSX

    https://www.enthought.com/roundup/enthon/issue35

The installer is reported to fail on 10.4.2

    https://www.enthought.com/roundup/enthon/issue30

And finally there is a message suggesting it is possible to run MacEnthon on
OSX 10.4.4
