From Mail-DKIM changelog: 2007-10-04: Jason Long <jlong@messiah.edu> [...] * lib/Mail/DKIM/Verifier.pm: remove dependency on Error module From README: This module requires these other modules and libraries: Crypt::OpenSSL::RSA Digest::SHA Digest::SHA1 Mail::Address (part of the MailTools package) MIME::Base64 Net::DNS dev-perl/Error is not needed for >=dev-perl/Mail-DKIM-0.29
Fixed. Thanks.
