Thanks Marcus and Jim for the detailed instructions, however I still 
cannot get this to work!

This my python path:

address@hidden trunk]$ cat $PYTHONPATH
cat: /usr/local/src/gr-osmosdr/include/osmosdr/:/home/phil/bin

The path points to osmosdr_source_c.h.

And these are still the same errors:

Error 0:
Block - import_1 - Import(import):
  Param - Import(import):
    Import "import simple_fm_helper" failed.

Error 1:
Block - cur_freq - Variable(variable):
  Param - Value(value):
    Value "simple_fm_helper.freq_select(ifreq,preselect)" cannot be 
evaluated:
    name 'simple_fm_helper' is not defined

Error 2:
Block - rtext_0 - WX GUI Static Text(variable_static_text):
  Param - Default Value(value):
    Value "cur_freq" cannot be evaluated:
    name 'cur_freq' is not defined

Error 3:
Block - gr_freq_xlating_fir_filter_xxx_0 - Frequency Xlating FIR 
Filter(gr_freq_xlating_fir_filter_xxx):
  Sink - in(0):
    Port is not connected.

I'm at my wits end.
