If "make clean" and rebuilding doesn't fix it, then it sounds like you
have more than one version of GRASS on your system, and it's picking
up the wrong libraries.

That sounds like multiple versions.

Leave os.environ alone; create a new environment dictionary and pass
that to subprocess.Popen(), e.g.:
myenv = os.environ.copy()
myenv['DYLD_FRAMEWORK_PATH'] = '/var/tmp/XcodeBuilds/Release'
myenv['OSSIM_PREFS_FILE'] = '/Users/sasha/ossim_preferences'
output = subprocess.Popen(..., env = myenv).communicate()[0]
This isn't related to this specific problem, though, just general
Python coding advice.
