2.3 missing on OSX

[Laran Evans]

I just tried to run MacVim on OSX 10.5. It crashed with this:

Dyld Error Message:
  Library not loaded: /System/Library/Frameworks/Python.framework/
Versions/2.3/Python
  Referenced from: /Users/laran/Downloads/MacVim-7_2-stable-1_2/
MacVim.app/Contents/MacOS/Vim
  Reason: image not found

I posted to the MacVim mailing list and was told that that version of
2.3 should always be available because it comes with the OS.

I don't remember if I removed it for whatever reason at some point or
something. In any case, I have python installed now via MacPorts. I
have version 2.3 and 2.5 both installed.

So my question is, is there a way for me to fix the issue by re-
instating the default 2.3 location or something?

I'm not much of a Python person. So I don't really know where to start
with this one.

Thanks.
