That is the problem - the 'pp' thing. At pp compile time it didn't 
know you wanted PerlIO.pm (or PerlIO::encoding).

What is the _exact_ message?

But (if I understand how pp works correctly) the pp compiled thing 
does not look in the lib directory, only in the magical CODE() thing.
The CODE thing is a subroutine that finds the module in compiled-in
way.

It wouldn't - @INC is for directory names to look in not module names.
And a push() like that happens at run time.

 use lib "C:\\Perl\\lib"; 

might help, but I expect the equivalent was already in force anyway.

I _think_ if you add

use PerlIO qw(encoding);

To your script then pp will notice that PerlIO.pm and encoding.pm 
are needed.

(My pp like thing would.)
