[Discuss-gnuradio] failure to build some components and running usrp examples

[bellzii]

The following components were skipped either because you asked not
to build them or they didn't pass configuration checks:

gr-audio-jack
gr-audio-osx
gr-audio-portaudio
gr-audio-windows
gr-comedi
gr-video-sdl
ezdop
gr-ezdop

These components will not be built.

(all other critical components were built) 


I tried running the usrp_wfm_rcv.py  but i got 

Using RX d'board A: Flex 2400 Rx MIMO B
>>> gr_fir_ccf: using SSE
>>> gr_fir_fff: using SSE
audio_alsa_sink[hw:0,0]: Device or resource busy

  File "/usr/local/lib/python2.4/site-packages/gnuradio/audio_alsa.py", line
236, in sink
    return _audio_alsa.sink(*args)
RuntimeError: audio_alsa_sink

why is alsa not working does it have to with my RXF2400 daughter being not
in fm range??

thanks in advance
