inskape for FC4 extension error

[Eric Tanguy]

I installed inskape from extras repository and when i launch it, it
complains that extensions failed to load and in
~/.inkscape/extension-errors.log i have this : 
Extension "Sketch Input" failed to load because a dependency was not
met.
Dependency::
  type: executable
  location: path
  string: skconvert

Extension "Postscript Input" failed to load because a dependency was not
met.
Dependency::
  type: extension
  location: path
  string: org.inkscape.input.sk

  string: org.inkscape.input.ps

Extension "AI Output" failed to load because a dependency was not met.
