The only good reason I can think of is that both RPM and dpkg are semi-complex 
systems and will require anyone entering the problem space to fully understand 
them before they can be suitably bent to MacPorts' will.  I'm not saying that's 
an impossible challenge, certainly not, but it does constitute a barrier to 
entry that simply "starting small and working your way up" may avoid.  RPMs 
also have their own food chain, where SRPMs encapsulate the sources and 
building process and RPMs do the binary bit, and there may be some 
impedance-mismatch issues in having MacPorts take over some but not all of the 
work involved.   I also expect this to be the part where Jeff jumps up and 
explains how he's embedded a complete, stand-alone Common LISP development 
environment into RPM 3000 which allows you to do everything, up to and 
including implementing EMACS, inside the packaging system itself. ;-)

Actually, the GPL had no bearing in why those were "rejected" (and I think 
that's too strong a word considering that package creation shims were done for 
both).  I think the real reason was sadly more prosaic:  We didn't have any RPM 
/ dpkg experts around who were really committed to making either of those 
systems work fully.

I think that's a good idea for all the reasons I explained in my first 
paragraph.  You can start simple and just add things incrementally until 
archives are "smart enough" to do the job, with the pkg(1) tool providing the 
installation harness.  Of course, another route might be to grab the latest 
version of that Darwin port of *BSD's package tools and make those do the job 
too since archives are already slowly mutating into *BSD packages today and you 
could also just finish the job, but I have a hard time recommending those tools 
to anyone given that I wrote most of the code and know how horrible they are.
