Like gnuradio-companion's dialog says, this looks like Python can't find
your GR installation.

Try running "python" and then type "import gnuradio". You shouldn't get
any errors if everything has been installed correctly:

$ python
Python 2.7.8 (default, Oct 18 2014, 12:50:18)
[GCC 4.9.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import gnuradio
>>>

If this fails, check where GR's Python modules got installed. Python
modules should be in a directory named "gnuradio" that has contents
similar to this:

$ ls gnuradio
__init__.py
__init__.pyc
__init__.pyo
analog
atsc
audio
blocks
...

Make sure that the directory above the "gnuradio" directory is in the
Python's include path (paths listed in PYTHONPATH and the default
include paths for your system).

For example, if you find
"/usr/local/lib/python2.7/dist-packages/gnuradio", try putting
"/usr/local/lib/python2.7/dist-packages" in PYTHONPATH.
