No, I mean adding an rpath with the path for these trouble makers into
"whatever" in gcc needs to find them. A specific rpath isn't tied to a
particular library, is it? For example if I build gcc using particular
revision of gmp in a particular spot (hacked to include an rpath to
find it). And then download and build a minor rev to gmp in a
different place and remove the original. If I tell the dynamic linker
about the new gmp will gcc still run?

Thanks for the link. I'll take a look.

Is this env in the install manual? I'll take a peek. Might give it a try.
