Hunnypot has a few prerequisites:
a DBI compatible SQL server (MySQL, MSSQL, ...)
a DBI driver (mysql, Sybase, ...)
perl 5.6.1 (or above)
and several perl modules, inculding:
Net::DNS, IO::Socket::INET, IO::Multiplex, and DBI
If either of these modules are not on your system, you can easily get
them by searching on http://search.cpan.org.

cp hunnypot.pl /usr/local/script
chmod 755 /usr/local/script/hunnypot.pl
chown root /usr/local/script/hunnypot.pl

Now set up your database and table.  Hunnypot doesnt need it's own 
database; it'll work fine if you want to give it it's own table in a
generic database.  If you're using MySQL, you can create your table by
simply running the command in the contrib/hunnypot.mysql file.  Others
can review this file to find out how to set up the table on their own.

You now have to choose how to start Hunnypot.  You can either 
configure your startup scripts to start it for you, or, I'd recommend
running Hunnypot under DJB's daemontools (available at:
http://cr.yp.to/daemontools.html )

Notes:
DEBUG = set to 1 to send more output to logs
DBUN = the username to connect to the sql database with
DBPW = the password for the sql username
DBSERVER = the hostname of the sql server
DRIVER = the DBI driver to use (mysql, Sybase,..)
DBNAME = the name of the database that contains the hunnypot table
HELONAME = a name to tell SMTP clients your hostname is
LISTEN_IP = IP Address to listen on (0.0.0.0 will listen on all)

#### FOR STARTUP SCRIPTS ONLY ####
edit the contrib/rc.hunnypot, and set the variables as needed
 cp contrib/rc.hunnypot /etc/rc.d/hunnypot
(or cp contrib/rc.hunnypot /etc/rc2.d/S99hunnypot)
make sure you set up a cron to cp /dev/null /var/log/hunnypot.log

#### FOR DAEMONTOOLS ONLY ####
edit the contrib/daemontools/run file, and set the variables as needed
 mkdir -p /service/hunnypot/log/ /var/log/hunnypot/
 chown nobody /var/log/hunnypot
 cp contrib/daemontools/run /service/hunnypot/run
 cp contrib/daemontools/log/run /service/hunnypot/log/run
 chmod 755 /service/hunnypot/run
 chmod 755 /service/hunnypot/log/run

####  That's It.

 (for daemontools): tail -f /var/log/hunnypot/current
or
 (for startup script): tail -f /var/log/hunnypot.log

and:  SELECT * FROM hunnypot
