In DarwinPorts, python is installed as a shared library 
(non-framework), just like it would be under other unices. I think a 
good way to check for Mac OS-specific is something like

try:
     import MacOS
except ImportError:
     python_type = 'not macos'
else:
     if MacOS.linkmodel == 'framework':
         python_type = 'framework'
     else:
         python_type = 'not framework'

(run in the python you're testing, of course)

According to the docs, MacOS.linkmodel is 'framework', 'static', or 
'shared'; a DarwinPorts python should be 'shared'.
