[Pythonmac-SIG] Leopard easy_install chokes on appscript egg

[has]

Hi all,

Just ran into the following problem when trying to install appscript  
0.18.0 into Leopard's default Python installation via easy_install  
(setuptools 0.6c3):

has$ /usr/bin/easy_install appscript

Two things:

1. Any ideas on why it's selecting the .tar.gz version rather than  
the .egg? (Note: the egg was built using my own Python 2.5  
installation, rather than the Apple one.)

2. I get the above traceback when easy_install tries to use the source- 
based appscript. This occurs with Leopard's own Python 2.5 and the  
Python 2.4 installation I keep around for testing purposes. Any  
guesses on what's going wrong? I'm not that familiar with setuptools  
and its error reporting leaves something to be desired, so I don't  
even know if the problem lies with it or appscript's setup.py script.



Thanks,

has
