Replicating DOA estimate experiments with FMComms5 and GNU radio

Hi All,

I have been trying to repeat the DOA estimation experiments done with FMComms5 board with the help of GNU radio. I was able to find a lot of work done at - (Great work, and thanks a lot Travis!). However I have been facing some hiccups while running the code. 

After making sure I installed all the dependencies, on running most of the codes located in the /apps folder, I get the error - 

File "/usr/local/lib/python2.7/dist-packages/doa/", line 31, in <module>
    import PyQt4.Qwt5 as Qwt
ImportError: No module named Qwt5

Which is weird, since PyQt4 is installed at the same location. I tried reinstalling PyQt4 but then there is some mismatch with SIP. I then attempted running Python 2 from the terminal and importing Qwt5, but I get the same error.

Any help or advice is greatly appreciated!
