[Pythonmac-SIG] How to install packages?

[pythonmac at gisborne.emailuser.net]

Panther. Latest update.

Installed MacPython extensions for Panther.

Installed wxPython for Panther.

Go to /Applications/wxPythonOSX-2.4.1.2.

Open Demos. Double-click on arbitrary demo. See this:

$ "/usr/local/bin/pythonw"   
"/Applications/wxPythonOSX-2.4.1.2/demo/wxButton.pyc"  && echo Exit  
status: $? && exit 1
Traceback (most recent call last):
   File "/Applications/wxPythonOSX-2.4.1.2/demo/wxButton.py", line 2, in  
?
ImportError: No module named wxPython.wx

Wonder about how to install packages on OS X.

Search archives. Find assertion that packages go in

/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/ 
site-packages

Find followup posting in February by Bob saying that:

site-packages itself is a  symlink to /Library/Python/2.3

Become further confused, because this is quite clearly *not* the case  
on my system -- the two folders have utterly disparate content.

Try copying wxPython folder from /Library/Python/2.3 to  
/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/ 
site-packages

Try to run demo again. Same result.

Become utterly confused, decide to ask mailing list. Aim to put the  
answer on the FAQ, where it clearly belongs.
