Question about Devel::Cover

[Himal]

Hi,
I am trying to do covegage on perl (5.8.0)
And have installed Devel::Cover 2.0 from Cpan. But when I try
perl -Mdevel::Cover temp.pl I get :
"Can't locate loadable object for module Devel::Cover in @INC"
and
"Devel::Cover: Can't find file "../../lib/DynaLoader.pm"
"Can't locate auto/Devel/Cover/set_criteri.al in @INC"

I am not sure how to go further.
Any help will be great.
Regars,
Himal.
