 Replying to [comment:1 jeremyhu]:
 > The goal with the clang toolchains (as opposed to gcc toolchains) is to
 be as compatible with the host as possible.  As such, I don't intend to
 have -stdlib=libstdc++ refer to the MacPorts-provided libstdc++.

 do you think about that?
 That would certainly work for what I need.[[BR]]
 I would submit a patch, but I have no idea how to do this.

 Replying to [comment:3 jeremyhu]:
 > Note that if that's non-trivial, we could do it your way (with a
 variant), but let's have it add the dependency on libgcc.
