Looking forward to the patches, I'm just sourcing environment scripts as
well.

Hi,

this is one reason why i never stopped using my toolsbox to bootstrap
portage: it creates environment-scripts, besides others containing those
LD_LIBRARY_PATH bits. And well, this is called SHLIB_PATH on HP-UX and
LIBPATH on AIX.

And for the running portage, i've some patches to let portage
dynamically extend the list of extendable variables with values
from /etc/env.d/ files.
In combination with some baselayout-packages, which do those
configuration through /etc/env.d/, i'm able to inform portage to dupe
the value of LDPATH into LD_LIBRARY_PATH, SHLIB_PATH or LIBPATH,
depending on the profile, which unmask the correct baselayout for a
specific platform.

Patches/ebuilds coming soon ...
