The first step is to find out why the symbol is missing. Try:
ldd /usr/local/lib/libgnuradio-filter-3.7.3.so.0.0.0
and look for a missing shared library. That will tell you what went
wrong. Looks like maybe they changed the version or something.
The quickest way is likely to reinstall it all with pybombs.
