[Pythonmac-SIG] 2.3 vs 2.4

[Daniel Lord]

It is _not_ a good thing to remove Apple's Python. Don't panic though.

First, let's stop this from happening to anybody else...
Can you tell me where those instructions are that recommend that on  
Python.org? I believe they refer to a previous _MacPython_  that was  
installed which is not the same as _Apple's Python_ --perhaps that is  
what confused you? If so, please say so and tell me where the text is  
that confused you. (NOTE TO SELF: we might want to make that  
distinction more clear)

There are applications (MotionBuilder is obviously one I now know)  
that look for Python, not on your environment path like IMHO they  
should, but instead embed the path. Someone with credulity (i.e. not  
me;-) should recommend Alias research adopt that practice.

First let me try and help you:
What did you do to remove it? If you just deleted symbolic links,  
great--put them back ;-).
In the future, rather than removing things, try changing symbolic  
links in your path--that way recovery is rather simple.
If you deleted files, the best thing to do is to to find another Mac  
running the same version of OS X you have and copy the Python  
framework back.
If you cannot, I am not sure how to help.

If you were successful in restoring things, then allow me to tell you  
what you should do in the future:
The recommended approach (and it used to be the default on install  
for MacPython--I beleive it may still be but is optional now) is to  
install MacPython in /usr/local/bin leaving Apple's Python 2.3  
intact. Then you put /usr/local/bin in your path ahead of /usr/bin  
(the location of the 2.3 python binary). then applications with hard  
links to /usr/bin/python don't break.
