I solved the link errors to the symbol: "boost::program_options::value_semantic_codecvt_helper<char>::parse(boost::any&, std::vector<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::allocator<std::basic_string<char, std::char_traits<char>, std::allocator<char> > > > const&, bool) const
by reinstalling boost 1.4.1 from MacPorts without the "+debug" option. With this fix, I can built both Wt 3.0.0 and Wt from git on Mac OS X 10.6.2 I'm now using CMake 2.8.0 from cmake.org, rather than installing it from MacPorts, although I don't know if this made any difference.
