Re: Problems executing MayaVi2

Hi Prabhu

If alternatively I successfully do

  > easy_install ETS[nonets]

would it be easy later on to uninstall packages (eggs) not needed by
MayaVi, such that no other dependencies are broken? I am not familiar
at all with python eggs, but they seem to be very similar to RPMs.

Cheers,

Santiago
