Gnuradio package missing pieces?

Question

Trying to get gnuradio working with my bladeRF but there appears to be an issue w/ the v3.7.2.1-1 package I installed from [community].
Specifically, when I attempt to lauch the spectrum analyzer tool, uhd_fft, it fails with the message:
"Error importing GNU Radio's wxgui. Please make sure gr-wxgui is installed.".
Now, I do have wxPython (for python 2.x) installed, and uhd_fft is using python2:
>head -1 /usr/bin/uhd_fft
#!/usr/bin/python2
So gnuradio isn't using the system wxPython.  I looked at the source for gnuradio (3.7.2.1), and noticed it's got a ton of stuff that's not in the arch package.  Here's a sample of dirs in the src but not the package:
gr-analog
gr-atsc
gr-audio
gr-blocks
...snip...
gr-vocoder
gr-wavelet
gr-wxgui
Including the missing gr-wxgui.  Any idea what's going on here?  Any idea how to actually get gnuradio working from the arch package?

testcore,
I was able to reproduce your problem and I found bug/PTR 38293 against the gnuradio package for the issue described.
It sounds like you could recompile. Perhaps using Pacbuilder could help in the effort.
For me, the simplest and quickest way around this was to use the aur gnuradio-git package and to install the dependencies necessary to compile with gr-wxgui support. If I recall correctly I needed to install Cheetah templates, wxpython, qt4, python2-opengl.
Cheers,
