Looks like some URI module is broken. You'll have to install the URI module without CPAN.pm shell, using `make && make test && make install`.

My URI::_foreign looks like it is deprecated and all functionality is in URI::_generic, for it only require()s that module and puts it into @ISA and nothing more, URI::_generic inherits the "host" method from URI.pm itself. One of those dependencies must be broken...
