ptkdb for CGI script

Hi

Using ptkdb I would like to debug my CGI script. My server and client are same machine only. This is my script:

 #!/usr/local/bin/perl -d:ptkdb
 BEGIN {
     $ENV{'DISPLAY'} = "10.40.14.106:0.0";
 }
 Then my code
 .
 .
 .

But, if I open the script in my web browser, I am not getting any ptkdb window. ptkdb works fine at command line, but it is not showing up when i access the cgi thru browser.

This is what I have configured for the xhost in my system:

 xhost
 access control anabled, only authorized clients can connect
 INET:10.40.14.106
 (where 10.40.14.106 is my ip)


Any help is greatly appreciated.

Thanks
Srikanth
