Likely you need fix your search path for the dynamic linker to include the directory of the libraries of the gcc port you are using (I think for the gcc* ports this is intended to be done via ldconfig(8), i.e. the `ldconfig -r` output needs to include the libstdc++.so.6 of that gcc port) or to include it before the base counterparts. If that doesn't solve your problem you should talk to the port maintainer. Marius
