Default instructions fail on OSX

[roughcut]

Following the instructions here (https://devcenter.heroku.com//articles/proximo#determining-your-static-ip-address) with Rails 3.2.9, Ruby 1.9.3 on OSX yields the following:

india:roughcut (dev) dr jm$ foreman start
10:31:31 web.1  | started with pid 80093
10:31:31 web.1  | You must first install Proximo:

10:31:31 system | sending SIGTERM to all processes
SIGTERM received

This is because readlink -f $0 is not a valid command on OSX and the installed bin/proximo is not a soft link but rather an executable, so readlink bin/proximo would return nothing anyways (when assigning a value to $DANTE_DIR) -- so dante/socks.conf is not found.

The initial error "You must first install Promixo" is because the PROXIMO_URL environment variable is not being set by Heroku for some reason. Manually specifying it gets us past this error but not the readlink error(s).

Thanks!

We had to perform the following steps to get proximo working:

1. Removing readlink -f from bin/proximo shell script
2. Add the environment variable PROXIMO_URL locally on our development box.
