The Hardware Profiler is only used if users opt in. If you don't recognize
it, that's probably a good sign (if the bindings aren't used.)
mythmetadatalookup uses ttvdb.py and tmdb.py. Not a problem if you don't use
If anyone has tools that they use with MythTV, and they exist in known
places (e.g. /usr/bin or /usr/local/bin or ~/bin etc.) then just grep
for "MythTV" in those directories/*.py to see if the bindings are in
use. Look for MythDB too. Although the .py suffix isn't always used.

I didn't test --without-bindings=python, but looking at configure,
it does turn them off. That should show up in the configure output.
"WARNING: disabling Python bindings; missing ..."
As mentioned in the 1st reply, just use --python=<yourPythonVersion.
Python v2 and v3 Bindings are available, the choice is made at configure
time. v2 support will go away in a future release.
