How to build a minimal standalone pkg ?

[Julien Narboux]

Hi,

I would like to build a standalone package of DigiKam using macports. 
The goal is to have an easy to distribute binary package.
I plan to install macports in a special directory for digikam (different 
from macports'default) and then build a dmg including digikam and all 
its dependencies using:
port mdmg digikam

But I think this command includes all the build dependencies of digiKam 
in the dmg and the dmg I get is 1.1go.
Is there a way to produce a mdmg including only the runtime dependencies ?
Does anyone has ever built a standalone .dmg package of a KDE app ?
