The odd thing is gnuradio-companion should have complained if the
PYTHONPATH wasn't being set.

So it's being set somewhere else.

How do you know you only have one installation of gnuradio installed?

And where did you get the gnuradio you installed?

In any case type

which gnuradio-config-info

and

gnuradio-config-info --prefix --sysconfdir --enabled-components
--builddate --prefsdir --version

Then you need to find your grc.conf file and delete it

find $HOME -name grc.conf

Then try to start gnuradio-companion - don't add anything to the flow
graph. Just see if it starts up properly.
