[Pythonmac-SIG] How to import libraries on Mac OS X?

[Eric Wichterich]

Thank you Ronald,

I figured out that there is a problem with Apache and CGI, not with  
importing the library anymore. There is something Apache doesn't like.  
I only get the two different errors: Malformed header - or - premature  
end of file. These scripts work fine on a linux server with Apache...

I'll keep working on it. It's just frustrating.
