That's great to hear. Do you think we should change the Install Guide 
(to mention both gcc and python-dev)?

The "Exception: Duplicate feature: 'SystemDictionary'" is a KForge error 
that arises when Apache/mod_python is having trouble with the KForge 
code. (KForge is trying to register the system dictionary feature with 
the application, but the system dictionary feature is already 
registered. This seems to be the affect of mod_python trying to reload 
the code, having trouble, and then carrying on. It would be nicer if 
mod_python would return the same error each time but it doesn't, 
probably for some good reason.)

Try restarting Apache, then reloading the page. If there's a problem, 
you may see a previous error in the Apache error log. There might also 
be some information in the kforge.log.

It could be something to do with running KForge with Python 2.6, or 
permissions on the log file, or any number of things. Anyway, restart, 
reload, and catch the first error.

Best wishes,
