Jim still having long RPATH issues.
- Todd will try this with Jim's pull request code to reproduce.

Discussion

Mark Miller asks whether we can query name mangling in Fortran compilers
- Actually an interesting ABI issue because compilers can support multiple underscoring schemes.
- Spack should probably figure out and ensure consistency.
- Currently can build an ABI-incompatible version of the same library and Spack won't know b/c it doesn't understand mangling.
Mark Miller asking about why Spack can't find manually installed packages in opt/spack
- How could we support this?
- Matt already implementing support for packages outside the spack build space, but installing into Spack's build space violates the rules. Essentially adding a foreign library to a managed area.
