Comment 4 for bug 185472

I am not sure I understand the reported bug but mayavi2 will not install on Hardy for me any more (it used to till a few days ago).
I will appreciate a solution...
(I deeply appreciate the introduction of such a variety of scientific packages, especially python based - excellent work!!!)
