installation mac os x

Can someone help me with the problems I have with installing  
PyBlosxom on Mac OS X 10.4.7? I browsed through the archives but  
still had no succes in various attempts.
Thanks for any feedback.
Gert

This is what I did:
1. downloaded: pyblosxom-1.3.2
2. cp ~/Desktop/pyblosxom-1.3.2/web/pyblosxom.cgi /Library/WebServer/ 
CGI-Executables/
3. cp ~/Desktop/pyblosxom-1.3.2/web/config.py /Library/WebServer/CGI- 
Executables/
4. chmod a+x /Library/WebServer/CGI-Executables/pyblosxom.cgi
5. mkdir /Library/WebServer/Documents/PybEntries
6. mkdir /Library/WebServer/Documents/PybEntries/entries
7. mkdir /Library/WebServer/Documents/PybEntries/flavours

8. In "config.py" I changed the lines
	py["codebase"] = "/Library/Webserver/CGI-Executables"
	py['datadir'] = "/Library/Webserver/Documents/PybEntries/entries"

9. Created a document: test.txt with some text and saved
this in "/Library/WebServer/Documents/PybEntries/entries"

10. Started up a browser:
---> Result request for: http://127.0.0.1/cgi-bin/pyblosxom.cgi
=======================
Internal Server Error
=======================
11. In pyblosxom.cgi I uncommented line (8):
	import cgitb; cgitb.enable()

---> Result request for: http://127.0.0.1/cgi-bin/pyblosxom.cgi
================================================================
A problem occurred in a Python script.
Here is the sequence of function calls leading up to the error,
in the order they occurred.

/Library/WebServer/CGI-Executables/pyblosxom.cgi
    25     sys.path.insert(0, cfg["codebase"])
    26
    27 from Pyblosxom.pyblosxom import PyBlosxom
    28
    29 if __name__ == '__main__':
Pyblosxom undefined, PyBlosxom undefined

ImportError: No module named Pyblosxom.pyblosxom
       args = ('No module named Pyblosxom.pyblosxom',)
