"""fixapplepython23 - Fix Apple-installed Python 2.3 (on Mac OS X 10.3)
|
|
|
|
Python 2.3 (and 2.3.X for X<5) have the problem that building an extension
|
|
for a framework installation may accidentally pick up the framework
|
|
of a newer Python, in stead of the one that was used to build the extension.
|
|
|
|
This script modifies the Makefile (in .../lib/python2.3/config) to use
|
|
the newer method of linking extensions with "-undefined dynamic_lookup"
|
|
which fixes this problem.
|
|
|
|
The script will first check all prerequisites, and return a zero exit
|
|
status also when nothing needs to be fixed.
