Firstly can I say thanks for your efforts, I certainly appreciate it, and 
the same for the other Gentoo/OS X devs. It is a tough gig.

Grobain, he reason this approach was taken (and this can be found in the 
list archives and forum), was that there was no alternative. The mythical 
pathspec was supposed to provide it. And, significantly, pathspec wasn't 
going to be needed to have a Gentoo/Darwin distro, anyway.

Kito, because of Gentoo/Darwin, this is not futile. And it saves space on 
your own machine. OS X has a decent binary package manager, why not 
exploit it? Updating a dot release on OS X is easier than emerge -Du 
system.

And if portage acquires the ability to pull deps from several prefixes 
(which is apparently part of the plan) it sacrifices nothing to use OS X 
deps.

There are two problems here: one is the vendor deps, i.e. the present 
practice of package.providing deps that are not equivalent to the ones OS 
X provides. This problem goes away as soon as we get ebuilds that can 
produce some of apples opensource packages that we use as deps. Apple 
being apple, this was always a big ask, but darwinbuild should help.

The second problem is that devs now have the job of making sure that the 
portage tree is portable: ebuilds have to work with Portaris, 
Gentoo/Darwin, Gentoo/BSD (a lot like Darwin), as well as Gentoo/Linux. 
This means a few more guidelines for writing ebuilds, but adds great value 
to the portage tree.

Exactly. And this is not new, see the ML archives for the threads on 
"optional os x packages" and "zip, and more, in package.provided", etc.

Would you use a GNU userland (like GNU/Darwin) or an apple one (like 
OpenDarwin and OS X)?

The reason I ask is that the former might mean leveraging the existing 
portage tree, whereas the latter might mean creating ebuilds for apple 
packages, thus solving the old package.provided problem.
