How to invoke a module installed locally?

umasuresh has asked for the wisdom of the Perl Monks concerning the following question:

Hi Monks,
I am trying to invoke the ptkdb.pm module which is installed locally using the following command:

perl -d:ptkdb my_perl_script.pl
[download]

This is what I tried so far:
After making a softlink of the two directories required for using this module (Devel, Tk) in the directory that I am running the script:

perl -d:ptkdb my_script.pl 

couldn't connect to display ":0" at /usr/lib64/perl5/vendor_perl/5.8.8
+/x86_64-linux-thread-multi/Tk/MainWindow.pm line 55.
MainWindow->new() at Devel/ptkdb.pm line 1147
Can't call method "setup_main_window" on unblessed reference at Devel/
+ptkdb.pm line 4151.
[download]

How do I make this work? Thanks much!

Is your X server running on the :0 display?	[reply]

Hi Choroba, Thanks much for your hint. Following your hint and my colleagues: `ssh -X remote_location` [download] This enabled X11 forwarding and then when I invoke the `perl -d:ptkdb script.pl` it works like a charm!	[reply] [d/l] [select]

yes....ssh sets up the variables in your terminal session for the X server/client communication to work. you could have set those up yourself as well. X needs to know the endpoint for the communication..which in the end is an ip address and port number. the hardest line to type correctly is: stty erase ^H	[reply]
