[boost] 'unnamed_Path' was not declared in this scope

Hi! While building a package against boost I receive the following message: /usr/include/boost/filesystem/v2/operations.hpp: In function 'Path boost::filesystem2::current_path()': /usr/include/boost/filesystem/v2/operations.hpp:534:14: error: 'unnamed_Path' was not declared in this scope Is this an error in boost and how can I overcome it?
