Thanks for the reply.

Here what it says. I cut it to what I think is significant.

This is perl, version 5.001

Unofficial patchlevel 1m.

Copyright1987-1994, Larry Wall

Win32 port Copyright (c) 1995 Microsoft Corporation...(and other details)

Perl for Win32 Build 110...(and other details)

And btw, I build my script in strawberry.

Yeah, even perl 5.001 should come with strict ... if you look at http://perl5.git.perl.org/perl.git/tags it says 19 years ago perl-5.001 and it includes a strict.pm

19 years ago is 190 years ago in computer time :)

Not even the mighty cXXXpan can help you, it only goes back to CP5.5.3AN: the Comprehensive Perl 5.5.3 Archive Network

Many basic tools like ExtUtils::MakeMaker require at least perl 5.006

Upgrading is not an option? Good luck with that, 190 years, so sad :)

This message is obligatory :) Yes, even you can use CPAN, A Guide to Installing Modules, Top 11 (GOOD) reasons not to use someone else's Modules, Top Seven (Bad) Reasons Not To Use Modules

http://citrusperl.com/ is binary distribution of perl for mac/linux/windows that is portable/relocatable ...

Yes I had checked and it has strict.pm. I don't know why that error comes out.

I think I'll have to upgrade to a newer version to work this out. Again thanks for the wonderful insights you had provided regarding this problem.

You ran perl -v which is not the same as what was asked for: perl -V.
