It's slightly challenging to attempt remote diagnosis of this type of issue; at first glance I thought this might just be an easy one (need to run ldconfig, perhaps; or a need to set the proper environment  variables, in particular PYTHONPATH).

Those could still be causing this issue, but I'm wondering now if it's not more likely to be a version incompatibility.

The old (pre GR 3.7.x) versions of op25 that were built from SVN were imported into python thusly:
   from gnuradio import op25
However now the new latest version of op25 (installed via git and perhaps built via pybombs) is imported like this:
   import op25

Your error message suggests the old version (which may be the only one compatible with Balint's gr-baz stuff; not sure).

So as a preliminary test, could I have you run a simple test; open the python interpreter interactively [just type python], and try
        import op25
at the python >>> prompt.
--please report the result --  do you get an error on this?
