Well, I guess that is a typo but FWIW I'd like to mention that VTK
does not depend on GTK and does not use it at all.  There is a pyGTK
widget that can embed a VTK render window but that is a different

Thanks for the compliments on MayaVi. :)

As regards the MayaVi license, MayaVi was developed for the community
so I didn't want someone to take the MayaVi codebase, use it for their
own purposes and not give back anything in terms of code to the
community.  That is why I chose the GPL.  However, the GPL does force
everyone else who links to it to be GPL.  I guess LGPL might also work
but I really don't know.  I'll try to give it some thought.  Anyway, I
am not sure you want to put all packages into one huge super package. 
It would be a nightmare to package/distribute!  I'd really pity the
person who'd have to maintain such a beast.

p.s. Please dont cc me in on replies.  My ISP has proved to be
incredibly incompetent and has not fixed a stupid DNS problem for the
last 5 days!! *Sigh*.
