 Macports for Python and pip,
compiled from source tarball for Tor.

is 'command' like 'which'? That failed - I tried all the usual places
like /opt/local/bin where Macports puts things.
But:

 I wouldn't have known about (and still don't) $PYTHONPATH - I don't use
 Python for anything else, it's just a black box to me.
I did find obfsproxy at
/opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/obfsproxy
eventually (I was expecting something larger than 401 bytes) and have
made a symlink from /usr/bin/ to ease access.
 Now that I can run it, will it be ok running as the same user as my
 (unpriviliged) Tor process? I assume the 
ServerTransportPlugin obfs3 exec /usr/local/bin/obfsproxy managed
line in the torrc will result in obfsproxy running as a child process?

Let's not try to run before we can crawl - see my other thread
'Non-standard Bridge' (might be working but no entry in Globe yet). 
One unknown programming language at a time please.

Thanks!
