Installing Mayavi with Pip - No Module Named Vtk

I want to use Mayavi.

Situation

• I use a MacBook Air, with OSX 10.7.3.
• I use Python 2.7.2
• I have virtualenv installed. But I have not used it for this installation.

I've manually installed all it's dependencies, including VTK.

For VTK, I followed its installation guide and installed the python wrapper.

Now if I open a new terminal window and open python, I can import vtk without any error.

Problem

I try to install Mayavi with the following command:

pip install mayavi

But the following error occurs:

I think the problem is with vtk.

Can anyone help me?
