Recommended versions of Perl modules?

[Ralf Hildebrandt]

Aug 21 13:22:08 mail amavis[17712]: Module Unix::Syslog        1.1

Looking at the INSTALL document seems to suggest some versions:

Archive::Zip   (Archive-Zip-x.xx) (1.14 or later, currently 1.23)
Compress::Zlib (Compress-Zlib-x.xx) (1.35 or later, currently 2.008)
Compress::Raw::Zlib (Compress-Raw-Zlib) (2.017 or later)
Convert::TNEF  (Convert-TNEF-x.xx)
Convert::UUlib (Convert-UUlib-x.xxx) (1.08 or later, stick to new versions!)
MIME::Base64   (MIME-Base64-x.xx)
MIME::Parser   (MIME-Tools-x.xxxx) (latest version from CPAN - currently 5.425)
Mail::Internet (MailTools-1.58 or later have workarounds for Perl 5.8.0 bugs)
Net::Server    (Net-Server-x.xx) (version 0.88 finally does setuid right)
Digest::MD5    (Digest-MD5-x.xx) (2.22 or later)
IO::Stringy    (IO-stringy-x.xxx)
Time::HiRes    (Time-HiRes-x.xx) (use 1.49 or later, older can cause problems)
Unix::Syslog   (Unix-Syslog-x.xxx)
BerkeleyDB     with bdb library (preferably 4.4.20 or later)
Mail::DKIM     (Mail-DKIM-0.31 or later)

But for example Compress::Raw::Zlib, MIME::Base64 and  IO::Stringy are
not reported at all. Mail::DKIM on the other hand seems to be split into
Mail::DKIM::Signer and Mail::DKIM::Verifier

Are these recommendations still valid (especially regarding the
version numbers). And: Is there an automatic check for "version at
least xyz" built in?
