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? > See http://gcc.gnu.org/faq.html#rpath for why GCC doesn't set rpath > automatically, unlike some other compilers. > Thanks for the link.

I'll take a peek. Might give it a try. kevin
