I didn't had a look at it, just some comments about some parts you explained.

This will probably fail if LD_LIBRARY_PATH is used, or if we are  
installing linuxulator ports.

What if a package is able to install on a subset, e.g. the linuxulator  
ports are for amd64 and i386?

What about DB corruption/loss? Do you keep the  
/var/db/pkg/<package>/xxx files even with pkgng and only use the DB as  
a way to speed up some work (so the DB corruption just requires to run  
pkg2ng), or are you lost of the DB is lost?

Bye,
Alexander.
