[Pythonmac-SIG] Python module installation on Leopard runs but doesn't install

[Robert Anderson]

I am a new user to Python on  Mac (Leopard) and am having a problem  
installing modules. I have seen various mails about directory problems  
with Python Leopard and I am not sure if they relate to my particular  
problem.

I am running a factory installation of Leopard and command line Python  
appears to run OK. However, when I attempted to install a downloaded  
package, PYTZ for example, the installation failed with a message "...  
requires System Python to install...".

  From the Python website I found the following link concerned with  
installing additional items, in particular IDLE:

http://wiki.python.org/moin/MacPython/Leopard

   I followed the instructions and command line Python still works,  
IDLE works and the installations now appear to work, however, nothing  
appears to have been installed and the downloaded(?) modules cannot be  
imported.

Can anyone provide any suggestions on what I should try next?

Thanks in advance
