I have a lot of environment variables set in /etc/profile and ~/.profile 
which I need passed through to the Spyder environment. When starting from 
the terminal, this is not a problem because the python environment of 
Spyder inherits from the bash environment (which sources /etc/profile and 
~/.profile). However, in your script, since python is run from a 
non-interactive shell (OS application startup), the profile files are not 
sourced. To solve this problem I modified the script as follows:

#! /opt/local/bin/python

import os
import subprocess

envstr = subprocess.check_output('source /etc/profile; source ~/.profile; 
printenv', shell=True)
env = [a.split('=') for a in envstr.strip().split('\n')]
os.environ.update(env)

executable = '/opt/local/bin/spyder'
arguments = [executable]

os.execve(executable, arguments, os.environ)

the check_output executes the source commands, after which I tell it to 
output all the environment variables which are then returned as a single 
string. The string is parsed into key-value pairs and used to update the 
os.environ dictionary.
