gnuradio: does propagatedBuildInputs make it work at runtime?

I still get this:

  $ ./result/bin/uhd_fft
  Traceback (most recent call last):
    File "./result/bin/uhd_fft", line 24, in <module>
      from gnuradio import gr, gru
  ImportError: No module named gnuradio

But maybe it is a different error than without propagatedBuildInputs?

By installing gnuradio with "nix-env -f . -i gnuradio" and adding
  export PYTHONPATH=$HOME/.nix-profile/lib/python2.7/site-packages/

I get this:

  $ ./result/bin/uhd_fft
