Updated to version 0.32.

Thanks to Julian Dunn in PR pkg/39031 for the notice. Since June CPAN-daily
messages were utf-8/base64 encoded and my procmail recipes did not handle
that...

Pkgsrc changes:
  - Does not require security/p5-Digest-SHA1 anymore.
  - Does not require devel/p5-Error anymore (already unnecessary for 0.29).

Changes since version 0.30:
===========================
Version 0.32 - released 2008-06-03
  * removed requirement for Digest::SHA1 (issue #1832549).
    We now use the more capable Digest::SHA module for SHA-1 and SHA-256.
  * bugfixes:
    * granularity checking should be case-sensitive (issue #1938112).
    * identity tag now uses quoted-printable encoding (issue #1839015).
  * API improvement:
    * implemented identity_source() for DkSignature objects

Version 0.31 - released 2008-04-14
  * some error detail messages were changed (see ChangeLog, 2008-01-10 entry)
  * by default, and when possible, DKIM signatures now omit c= and q= tags
    (they are optional tags) (issue #1878518)
  * DKIM and DomainKey signatures are now wrapped so that line breaks
    occur before colon (':') separators instead of after; this avoids
	confusing some broken MUAs (issue #1868648)
  * bugfixes:
    * "undef value" error when DKIM signature appears at end of header
      (issue #1878954)
    * use proper regexp for splitting email address (issue #1878994)
  * API improvements:
    * can specify a domain for fetch_author_policy() (issue #1879197)
    * can access a signature's public-key object (issue #1879215)
    * can specify an OpenSSL-private-key object for PrivateKey->new()
      (issue #1879209)

Version 0.30.1 - released 2008-01-24
 * bugfix:
   * email from cisco.com was failing to verify (issue #1878523)
