A few strange things that I spot at once:
Use either $ENV{'SCRIPT_NAME'} or $pod_urlpath$pod_progname, not both of them.

Is this really the path to "pod_searches.log"?
/home/lib/httpd/logs/pod_searches.log

Is this really the path to your header and footer files?
/home/user/public_html/cgi-bin/pod/

good luck
