Poudriere building far more ports than it should

[reko.turja at liukuma.net]

Hello list!

I finally took the hurdle and made a poudriere VM for building my ports 
instead of building them on target system. At first I did however build 
every single port I will need on the VM resulting on 240 or so ports.

Then I copied over my options, and the list of installed ports  etc. and 
started the build. For some reason poudriere wants to build a ton of extra 
baggage (360+ ports instead of 240.)

Is this expected and will the packages once built be without any extra 
cruft?
