Pex import problems

Hi all,
I'm trying to use Pex (http://pex.readthedocs.org/en/latest/index.html) to
include requests in a little script to ping a server from a machine that
doesn't come with pip (or much of anything, really) installed. I'm running
into problems outputting a pex file that depends on a local script.

I've got a command-line file, `client.py`, that can be called with a few
command-line options. I can run `pex -r requests -o client.pex --
client.py`, but when I try `./client.pex -h` I get an error about "no such
file or directory: '-h'".

Ok, next attempt: `pex -r requests -o client.pex -e client` -->
"ImportError: No module named client". I dug around in the code a bit, and
from what I can tell, `-e FOO` boils down to `__import__(FOO)`, which I can
do, both from the interpreter and from a test script. So what am I missing?

The only other option I can think of would be: `pex -r requests -o
client.pex` & then write a script that calls `client.py` from the pex
environment (i.e., `./client.pex client.py -h` or whatever), and bundle the
pex file, `client.py`, and the script together. But that seems like a
misuse of the tool, at best.

Alternatively/additionally: is there any mailing list/help source for pex?
It seems like a great project, but I've not been able to find many
resources out there, which is why I'm turning to you guys.


(Why not just install pip/requests on the target machine? Because this is
part of an effort to automate provisioning of a bunch of machines.)
(Why not use pants? Because literally all we need is requests, and that
seems like overkill.)
