 I'm having an issue where python scripts are loading the system numpy
 version instead of the MacPorts compiled version, this leads to the
 following error message:

 RuntimeError: module compiled against API version 6 but this version of
 numpy is 4

 and in some cases (e.g. scripts that use matplotlib) causes crashes.

 This has only started occurring on my system since I upgraded to OS X
 Lion.

 The fix so far seems to be to add the following code to the top of each
 script before loading numpy:

 sys.path.reverse()

 but this is extremely kludgy fix, and I never had to previously do this.
 My PYTHONPATH variable points to my local python repository and to the
 MacPorts site-packages directory only. Is there somewhere else I can tell
 python to stop loading stuff from
 /System/Library/Frameworks/Python.framework?
