Thank you very much for your help. It was a typo in my code that I had written "print" instead of "printf". I succeeded in reading the packages in the current directory where my script is.

However, I am running this case on a Cygwin platform and Perl interpreter cannot find the packages residing other than current directories although I declare them even within @INC. The directory of the said Perl script resides in 
/home/UTKU/devel/my_script

[download]
The said packages are located in 
/home/UTKU/devel/my_script/dir_one/my_package.pm
/home/UTKU/devel/my_script/dir_two/my_package.pm

[download]
Now the script tries following: 
#!/usr/bin/perl -w

BEGIN { push @INC, "/home/UTKU/devel/my_script" }
use Data::Dumper;
use dir_two::my_package;

print Dumper(\%my_hash);

Perl interpreter says me that my_hash is used only once, ie. it seems that the package has not been bound: 
$ ./my_script.pl
Name "main::my_hash" used only once: possible typo at ./my_script.pl l
+ine 9.
$VAR1 = {};

I know, interpreter takes the current directory into @INC but it also does not work. Can't I define packages with relative paths? The content of the package in /home/UTKU/devel/my_script/dir_two/my_package.pm is like in my first posting: 
##! /usr/local/bin/perl
package my_package;

require(Exporter);
@ISA = qw(Exporter);
@EXPORT = qw(
             %my_hash
          );

%my_hash = (
...
);

Is there any mechanism to switch on verbose messages during compilation/elaboration/linkage time of the interpreter to see what it is doing with the packages?
