It depends on the SONAME field inside the shared library.  The full name
of the lib needs to match the SONAME I think (which is libstdc++.so.2.9
in my build).

I realise that the naming doesn't follow the ports tree rules for shared
libs but it shouldn't cause conflicts if you use runpaths to point at its
location. I use '-Wl,-rpath=/usr/local/lib/gcc-lib/...' when I link stuff
that I want to use the shared lib.

Hopefully, this is only a short term measure until we get the beast
properly integrated into the build.
