No, not when the import is done, but rather when the source or sink is
constructed.

usrp_rx_file was removed from the respository a _long_ time a ago.
May I kindly suggest that you try the _current_ code.
See http://gnuradio.org/trac/wiki

If you want to use the usrp to receive wfm radio, try
usrp_wfm_rcv_pll.py
