Thanks a lot. I'll start playing with 10.6/x86_64 and see whether I
can convince @rpath to first resolve to the default system libc++ (on
10.7 or later, or on computers with libc++ from MacPorts for example)
and then to some shipped variant.

I used to build for 10.6/x86_64, 10.6/i386 & ppc on the same 64-bit
Snow Leopard VM. Doing C++11 cross-compilations for PPC is likely to
be mission impossible, so I'll need to find a proper PPC, but let's
see if I can get it working natively to start with.

Thank you,
