I am trying to edit a hosts file using the File::Tasks:Edit module

Why did you pick File::Tasks::Edit?

To me, File::Tasks::Edit looks like an unfinished thought, and since there are no real examples

http://search.cpan.org/~adamk/File-Tasks-0.07/MANIFEST

http://deps.cpantesters.org/depended-on-by.pl?dist=File-Tasks-0.07

I wouldn't pick it for any task :)
