P=python2: Command not found.

Warning -- New User.

I've cloned the git repository and installed it on 10.6.8.  When I try to run the command line example with the hostname, which is a ubuntu Ubuntu 10.04.3 LTS, replaced with the appropriate name

$ ./sshuttle -r hostname 0.0.0.0/0 -vv

The output is:

Starting sshuttle proxy.

Listening on ('127.0.0.1', 12300).

When I ssh to that machine, python is on my path:

$ type -a python

python is /usr/bin/python

Changing ssh.py to explicitly hardwire the path like this:

diff --git a/ssh.py b/ssh.py

index c4bf06e..75eb193 100644

+++ b/ssh.py

What did I miss?

What sort of computer are you trying to connect to? It seems like
maybe you don't have a sh compatible shell on this system; please try
the following commands and report the results here.

ssh hostname "echo \$SHELL"
ssh hostname "P=/usr/bin/python; echo \$P"

If hostname isn't your remote host, replace it with your real remote
host of course.

I've downloaded the app from Sshuttle VPN.app and it works fine on my mac and ubuntu system.  

Now for the debugging:

$ ssh hostname "echo \$SHELL"

/bin/tcsh

$ ssh hostname "P=/usr/bin/python; echo \$P"

P=/usr/bin/python: Command not found.

P: Undefined variable.

Ok, so I must be the last person on the world that still uses csh.

The tarball that worked was https://github.com/apenwarr/sshuttle/tarball/sshuttle-0.51-macos-bin and not https://github.com/apenwarr/sshuttle/tarball/sshuttle-0.60-macos-bin

Ok, good.

I would assume another option that should work would be to pass the
"--python /usr/bin/python" flag to sshuttle. If I read the code
correctly, it should use the first form of the pycmd, which I think
should work.

Thanks the --python option works like a champ.
