CPAN Install errors

EigenFunctions has asked for the wisdom of the Perl Monks concerning the following question:

I have two modules I'd like to use:

String::Similarity (The cksum does not contain the key 'cpan_path' for 'String-Similarity-1.04.tar.gz'.)
Text::vCard::Addressbook (The cksum does not contain the key 'cpan_path' for 'Directory-Scratch-0.18.tar.gz'.)

When I run CPAN, both end with a Checksum error as shown above.

Any idea's how to fix either or both?

Thanks,
EigenFunctions
