Thanks Bryan! If anyone is interested in testing the adapted pkg, there 
is a patch that can be applied to ports at 
http://people.freebsd.org/~nwhitehorn/pkg-new-abi.diff. It tries to make 
this transition as painless as possible by doing the following things:
1. Have pkg use e.g. FreeBSD:11:amd64 instead of freebsd:11:x86:64 as an 
ABI string.
2. Maintain the freebsd:11:x86:64-type strings as the "altabi" config 
variable.
3. pkg will install packages where the architecture ID matches either 
the ABI or ALTABI value, which means that new pkg can install packages 
made with the older version.
4. Patches the ports-mgmt/pkg Makefile so that the package for pkg 
itself is given a freebsd:11:x86:64-type architecture. This prevents pkg 
from choking on an update to itself and should, with the symlinks 
discussed above, make the transition painless and transparent.

Especially point (4) I'd appreciate testing on if anyone is generating 
private package repositories.
