Hi Suman- It looks like your PDL/perl install is not correct/complete.
PDL support is provided via the perldl mailing list so that other users can benefit from the results via web search. See "Get Help?" on the PDL web page, http://pdl.perl.org for how to join the list. I'll post to the list as a quick start...
