My apologies for not explaining clearly. This is the first time, I used or observed the CPAN modules. So, I installed ActiveStatePerl 5.16 version from web.And since I got the error related to unable to locate C/Scan.pm file while executing the code, I initially, downloaded the C-Scan-0.74.tar.gz and unzipped the folder. And did the following steps to install 
cd C-Scan-0.74\C-Scan-0.74
Makefile.PL   -> Here I got a Warning: prerequisite Data::Flow 0.05 no
+t found.

so, downloaded Data-Flow-1.02.tar.gz and followed makefile.pl followed by dmake install for both the modules.Still I was getting while compiling my perl code. But then when you asked me to explain the steps that I did, I just tried to add 
#use lib '../C-Scan-0.74/C-Scan-0.74/blib/lib';
#use lib '../Data-Flow-1.02/Data-Flow-1.02/blib/lib';

I could compile my code and things work fine. Now I shall check for my expected behavior out of the script and let you know. But if not for explaining you, I wouldn't have got things working.
