For non-homebrew Python, you need to amend your PYTHONPATH like so:
export PYTHONPATH=#{HOMEBREW_PREFIX}/lib/#{which_python}/site-packages:$PYTHONPATH
Even without the --pyqt option, you can display native VTK render windows
from python. Alternatively, you can integrate the RenderWindowInteractor
in PyQt, PySide, Tk or Wx at runtime. Look at
import vtk.qt4; help(vtk.qt4) or import vtk.wx; help(vtk.wx)
