Hi all,

I've a little problem, that I don't understand.

I testing a ebuild for vtk, but if I run emerge vtk, I become follow
error message:

Calculating dependencies

Depstring: dev-libs/vtk
Candidates: ['dev-libs/vtk']

emerge: there are no ebuilds to satisfy "virtual/python".


What is my problem.

Jens
