Linking of artsd fails with following errors:

soundserver_impl.o(.gnu.linkonce.d._ZTCN4Arts16SoundServer_implE52_NS_16SoundServer_skelE+0x204): undefined reference to `virtual thunk to Arts::SoundServer_base::_defaultPortsIn() const'
soundserver_impl.o(.gnu.linkonce.d._ZTCN4Arts16SoundServer_implE52_NS_16SoundServer_skelE+0x208): undefined reference to `virtual thunk to Arts::SoundServer_base::_defaultPortsOut() const'
soundserver_impl.o(.gnu.linkonce.d._ZTCN4Arts16SoundServer_implE52_NS_16SoundServer_skelE+0x20c): undefined reference to `virtual thunk to Arts::SoundServer_base::_cast(unsigned long)'

It works fine with gcc-3.0 release. Tried it with binutils 2.11 / 2.11.2.
I'm sorry for not providing a test case or some files from the package. Since it's a linker failure, I just don't know what kind of information you need.
