Perhaps I ultimately might have succeeded with that approach with enough recursion and time - but I ultimately went the route to install into /usr/lib instead as it just "wanted it that way" it seemed. And those libraries on SL are maybe good to have anyway, I rationalized...

Sounds like you've already tried all the things I was going to suggest.

I'm not aware of an option for that, though it's been awhile since I looked. You could possibly write a custom preflight script to check the library version of the existing libc++.

Yes I think so.
