@AnonymousMonk: Thanks for the reply! I believe it should be the latest one that came with Active Perl installation perl v5.16.2, but i am really not sure whether perl script is executed with this version or not. Moreover, i am relatively new to perl. Can you please let me know where i need to execute die $^X command?

Don't guess! The answer based on a guess has very little value as a response to a question from someone who's trying to help.

Try the command suggested in Re: Can't locate WWW/Mechanize/Firefox.pm in @INC and then tell us what it does (more on this -- how to execute -- is below).
And don't rely on external tools (either Check_INC.pl, which you don't show) nor where to tell you something about Perl that you can learn from your own Perl.

$ perl -v ; perl -e "print join \"\n\", @INC" can both help, or, use this little piece of code, which appeared here recently:

#! /usr/bin/perl
use 5.016;           #  adjust to suit the version identified from the
+ C:> prompt with <c>perl -v
[download]

use ExtUtils::Installed; my $module; my $inst = ExtUtils::Installed->new(); my (@modules) = $inst->modules(); foreach $module (@modules) { say "$module"; } </c>

The die $^X command gets executed from your command prompt, "C:\>" by preference (mine, an idiosyncracy) like this:
perl -E "die $^X;"
which will print something like this: C:\Perl\bin\perl.exe at -e line 1. where the part before the "(period)exe" is your path to perl.

... but at a quick glance, it appears from the content of your second code block that you're executing Oracle's 5.8 version of Perl... in which case, perhaps you didn't ask (Active State?) to add 5.16 to your path. So check your path too... is there an instance of Perl that's not in an Oracle directory?

Oh yes; @Annonymous Monk doesn't live here. But you can address Monks by name, by [name]... for example, to say your name to call you attention to this, I use that form of address: Pavan Renjal

Update: http://www.perl.com/pub/2002/05/14/mod_perl.html (under the heading "use(), require(), do(), %INC and @INC Explained" may be illuminating.

execute it as  diePerlPath.pl or perl -e " die $^X" so you can learn which perl is being executed

If you have a specific perl in mind, use an absolute path to it

And manage your %PATH% and associations so you're using the perl you want to use and not the other one

On win32 , shells, %PATH% and the like
