Won't install kpdf or kghostview

[handcrafted]

When I (using Spritz) try to install kpdf or kghostview, I can't use them.
They are listed under installed, but I can't use 'em, neither through the shell or the menu (they don't show up.)

Anybody who got a solution.

Thanks for the help.

What version of Sabayon are you using? They are normally there by default.
What message do you get if you enter either kpdf or kghostview in a terminal?
