Hi Harald,
if you want to have GNU Radio 3.7 & 3.8 on the same machine I recommend
to have both installed in a non-default search path for libraries.
Applications linking to GNU Radio then have to set LD_LIBRARY_PATH,
PYTHONPATH, GR_BLOCKS_PATH accordingly to point to the non-default

ou should check if it is in your pythonpath (e.g. python -c

folder and check with `ldd _mac_swig.so` (or similar) if the dynamic

Hey John,
