Thanks a ton for the helpful clues!

I think I've almost got my mind wrapped around this stuff - but just to be
certain, I'd like to clarify one thing.

My goal is pretty simple right now: I just want to create a second gentoo
installation on a separate partition, which is built from the ground-up using
uclibc - I'm still using the same platform/architecture ( i686 ), so I'm not
trying to target some different embedded device or anything, and I _do_
want to have a complete toolchain ( including portage ) on this uclibc-based
gentoo partion. 

My intention/aim is to only cross-compile the minimal environment necessary 
to be able to chroot into this new partition and begin emerging the rest of the 
software I want, as per a normal/standard gentoo install. Restated, I'm simply
after a uclibc-based/built gentoo system.

With that said, do I still need to emerge the libraries into a separate "SOMEXTOOLCHAIN"
ROOT? Or am I able to somehow just install those same libraries directly into
"YOUROTHERROOT" ROOT ( i.e., my separate partition, where I want my uclibc-based
gentoo to reside? )


THanks!
