First off Dear Monk please read the posting guidelines and consider adding <code> .. </code> tags around your code. Makes your post much more readable.

Secondly if you read the man page for the module in question you'd see:

       Example 3 - copying from remote machine to local host

        my $scpe = Net::SCP::Expect->new(user=>'user',password=>'xxxx');
        $scpe->scp('host:/some/dir/filename','newfilename');

I use Net::SCP::Expect all the time in my environment and there are some tricks to using it correctly but it works fine and lasts a long time.
