Migration from 3.7 to 3.8 OOT - module 'howto' has no attribute 'square_ff'

[Criss Swaim]

I am upgrading from gnuradio 3.7.2 to 3.8.2 and have run into a couple
of issues with my OOT modules not showing up in the python module.  So I
went back and walked through the HowTo tutorial to see it the tutorial
would work.  It fails also.

OS: Fedora 33

The libgnuradio-howto.so lib is in /usr/local/lib64

I have added the /usr/local/lib64 directory to ld.so.conf and ran the
sudo ldconfig to reload the lib paths, followed by make/make install. 

When the python howto module is created it does not have the square_ff
entry point:

> dir(howto)
> ['__builtins__', '__cached__', '__doc__', '__file__', '__loader__',
> '__name__', '__package__', '__path__', '__spec__', 'unicode_literals']
Any ideas on where to look next?  I am not sure if this is a path-ing
issue or is something wrong in the building of the python module.
