Hi Kevin,

I’ve run into this too.

The instructions tell you the solution after the build commands

change the “cmake” line to
cmake -DCMAKE_INSTALL_PREFIX=/usr .
and rebuild all

and do the copy step they suggest on site

https://wiki.analog.com/resources/tools-software/linux-software/gnuradio
(Either
cp -r /usr/local/lib/python2.7/dist-packages/gnuradio/iio /usr/lib/python2.7/dist-packages/gnuradio/ 
or
cp -r /usr/local/lib/python2.7/site-packages/gnuradio/iio /usr/lib/python2.7/site-packages/gnuradio/ 
or
some similar combination, depending on where your build files end up after install 
)

Good luck.

Glen
The packages can go into 4 different directories (on Ubuntu, maybe only 2 on mac) 

/usr/local/lib/python2.7/site-packages
/usr/lib/python2.7/site-packages

and

/usr/local/lib/python2.7/dist-packages
/usr/lib/python2.7/dist-packages

on Ubuntu
I’ve been copying all of the "site-packages" stuff into “dist-packages” 
and creating symbolic link from dist-packages to site-packages.

(Not really recommended, but I do it anyway).

Good Luck

New here and new to gnuRadio...
I'm attempting to get plutoSDR up and running on a Mac, I've installed gunradio and dependencies, I've also downloaded and built libiio, ibad9361-iio and gr-iio. Following this I've moved the block files across to the working directory. Running gnuradio-companion I can see the plutoSDR source & sink blocks, but when using them I get the following error: 

Traceback (most recent call last):
  File "/Users/m0khz/Desktop/top_block.py", line 22, in <module>
    from gnuradio import iio
ImportError: cannot import name iio

any help in where I'm going wrong much appreciated ....

Cheers Kevin

move the blocks between the necessary folders:
cp -r /usr/local/lib/python2.7/dist-packages/gnuradio/iio /usr/lib/python2.7/dist-packages/gnuradio/ 

This is where gnuRadio Companion is looking
/opt/local/share/gnuradio/grc/blocks

This is where the block were installed
/usr/local/share/gnuradio/grc/blocks/

So copied them across
Run gnuRadio-companion, IIO blocks are present, plutoSDR source and sink etc. are present, but get this error when tying to run the flow graph: 

<<< Welcome to GNU Radio Companion 3.7.13.5 >>>
