I'm using Mandrake 9.2, 10.0 "Official" and 10.1 "Community". 

I know that some are using Fedora Core 2, but I found that at least on
my P4 server, it wasn't ready for prime time.  There are definitely
some Debian users in the crowd too.

Thanks for pointing these out.

Just remove the mc4020 and gr-mc4020 directories after checking them
out.  Perhaps the checkout script should have --exclude=mc4020
and --exclude=usrp options to avoid checking out the hardware dependent
stuff.

The mc4020 driver needs a bit of work for 2.6.  Actually, I've got a
patch that's supposed to handle it, but it would be great if a single
tarball would build on both 2.4 and 2.6 kernels.  Anybody interested
in making this happen?

Good idea.

Where did you install wxPython?  If it's in
/usr/lib/python-2.3/site-packages, it should work as is.
In general you'll need PYTHONPATH=/usr/local/lib/python-2.3/site-packages 
for the default install of gnuradio.

Thanks again for the feedback.
