I'm trying to serve an existing Python 2.5 Pylons application on OS X Snow Leopard.

I've already installed Python 2.5 and set it as the default Python installation, installed paster, and installed the version of Pylons the app needs (0.9.6.1) as well as other eggs... but when I cd to the main folder and do "paster serve development.ini" I get the following:

File "/usr/local/bin/paster", line 5, in <module>
    from pkg_resources import load_entry_point

File "/System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/python/pkg_resources.py", line 2603, in <module>

File "/System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/python/pkg_resources.py", line 666, in require

File "/System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/python/pkg_resources.py", line 565, in resolve

pkg_resources.DistributionNotFound: PasteScript==1.7.3

I definitely have done "easy_install PasteScript==1.7.3" and I still get this error. Is there something really obvious I'm missing? Help?

Thanks in advance.
