    problems with an python cgi script in apache

    Hi, I have a python cgi script (called image.cgi) which works fine when I run it from the terminal as a py script, but when I try and run it from my apache web directory, I get the following error in the apache log.
    [Sun Apr 18 11:30:39 2010] [error] [client] Traceback (most recent call last):
    [Sun Apr 18 11:30:39 2010] [error] [client] File "/var/www/public_html/grooveshark/image.cgi", line 19, in <module>
    [Sun Apr 18 11:30:39 2010] [error] [client]
    [Sun Apr 18 11:30:39 2010] [error] [client] text_file = open("trackDB.txt", "w") # create the DB
    [Sun Apr 18 11:30:39 2010] [error] [client]
    [Sun Apr 18 11:30:39 2010] [error] [client] :
    [Sun Apr 18 11:30:39 2010] [error] [client] [Errno 13] Permission denied: 'trackDB.txt'
    [Sun Apr 18 11:30:39 2010] [error] [client]
    The error seems to say that the access to trackDB.txt is denied, but I have the file access at 755 (trackDB.txt will just have some text written to it).
    A regular python cgi script seems to work for example, a simplified version of my code with error catching...
    #!/usr/bin/env python
    import Image, ImageDraw, ImageFont, random, feedparser
    import cgi
    print "Content-type: text/html"
        print '''
    	<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
    	<meta content="text/html; charset=ISO-8859-1" http-equiv="content-type">
    	<script language = "JavaScript" src="grooveshark.js"></script>
    	<title>GrooveShark sig</title>
        print '<a href="http://google.com"><img src="test.png"></a><p>Hello</p>'
        print "world"
        print '''
        import cgi
    Works just fine.

    Does anyone have any ideas what is happening. BTW, the output in the browser is just a blank page.

    Check the owner (uid) of the file to make sure that it is the effective uid of what is running the script since -rwx- permission is given in that case. Write permission is not given to the group or others! Resolve that conflict.

    Errno 13 probably refers to a standard Unix error code (EPERM, I am guessing).

    Perhaps a google search helps too? I tried this:
