Solve the following python programming problem given the following code:
def replace_built(self, built_packages) : 
    'Return a copy of this resolvable set but with built packages.

    :param dict built_packages: A mapping from a resolved package to its locally built package.
    :returns: A new resolvable set with built package replacements made.
    ' 
    def map_packages(resolved_packages) : 
        packages = OrderedSet ((built_packages.get (p, p) for p in resolved_packages.packages)) 
        return _ResolvedPackages (resolved_packages.resolvable, packages, resolved_packages.parent) 
return _ResolvableSet ([map_packages (map_packages) for rp in self.__tuples]) 

    
    

    Fix the buggy line: return _ResolvableSet ([map_packages (map_packages) for rp in self.__tuples])
