[Mimedefang] Installation problem (MySQL)

[J.J. Day]

Hi,

I have been running Sendmail/MIMEDefang/SpamAssassin (with MySQL for bayes
and TxRep) for several years and want to update all to current versions. To
that end I did a fresh install of FreeBSD 10.3-RELEASE amd64 and installed
current packages when possible of all software. That resulted in:
   Perl 5.20
   MIMEDefang 2.78
   SpamAssassin 3.41
   MySQL 5.6 (5.7 resulted in a conflict with p5-DBD-mysql)
   MIME-tools 5.507 (from cpan)
   p5-DBI 1.634
   p5-DBD-mysql 4.033

However, when mimedefang starts it is unable to load MySQL and generates
this error:
May  1 01:00:08 mail-sys mimedefang-multiplexor[97185]: u41607H2097975:
Slave 0 stderr: plugin: eval failed: install_driver(mysql) failed: Can't

The MySQL perl modules seem to be installed correctly. A find returns:
   /usr/local/lib/perl5/site_perl/mach/5.20/Bundle/DBD/mysql.pm
   /usr/local/lib/perl5/site_perl/mach/5.20/DBD/mysql.pm
The perl structure changed from the operating system (perl 5.16) to the new
system (perl 5.20), but the permissions all match those of the current
system. 

Messages are processed and delivered properly except for skipping bayes and
TxReo tests so the spam scores are incorrect. I get the following error
output from the mimedefang slave during processing:
  plugin: eval failed: install_driver(mysql) failed: Attempt to reload
DBD/mysql.pm aborted.
  Compilation failed in require at (eval 1453) line 3.
   at /usr/local/lib/perl5/site_perl/Mail/SpamAssassin/BayesStore/MySQL.pm
line 653.
  rules: failed to run TXREP test, skipping:
  plugin: eval failed: bayes: (in learn) install_driver(mysql) failed:

  Compilation failed in require at (eval 1454) line 3.
   at /usr/local/lib/perl5/site_perl/Mail/SpamAssassin/BayesStore/MySQL.pm
line 653.

Did I miss something or has someone else had this problem? Or can someone
tell me how to find what to do?

TIA,

JJ
