Ubuntu 16.04 and mapnik - Python argument types in did not match C++ signature

Question

I have to install mapnik/mapnik-python on Ubuntu 16.04 (existing server) Both libraries compiled without any problem but python mapnik module doesn't work. After importing mapnik module i get error:

/home/user# python

C++ code defined as:

void register_datasources(std::string const& path)
{
    mapnik::datasource_cache::instance().register_datasources(path);
}

Python code:

def register_plugins(path=None):
    """Register plugins located by specified path"""
    if not path:
        if 'MAPNIK_INPUT_PLUGINS_DIRECTORY' in os.environ:
            path = os.environ.get('MAPNIK_INPUT_PLUGINS_DIRECTORY')
        else:
            from .paths import inputpluginspath
            path = inputpluginspath
    DatasourceCache.register_datasources(path)

I studied a boost library manual and found that std::string const& is a correct type declaration. It looks like this is a boost library bug.

Is there any way to get it working ? Is there any way to downgrade libboost_python in Ubuntu16.04 ?

Update: I looked into compiled _mapnik.so file using nm -C and found this:

U mapnik::datasource_cache::register_datasources(std::string const&, bool)

There is one more parameter in function added. Is it normal ?
