sorry no guru here.. I firstly supposed you have some misconfiguration issue with cpan client ( anyway check it with cpan o conf ), but effectively this module seems to be strange from cpan client point of view:

>cpan -D List::Util

Also cpan> i /File::Find/ show 67 packages but not File::Find and cpan> i File::Find shows No objects found of any type for argument File::Find

Weird..
