Wait until submissions for 15 are open. For now, build with python2 by 
default and make a separate python3 package or add a python3 switch. 
But, submissions are closed, so new packages are no longer an option :)

SlackBuilds target a default full install of Slackware. Your script 
should always use whatever is the default. If python3 is the default 
python version in a full install of Slackware, then your script should 
use that. This means for the upcoming Slackware 15 repo in SlackBuilds, 
your dpkt script should use python3 by default and if you want to add 
python2 support it could be a separate switch or you could create a 
separate  python2-dpkt script.
