I forgot to post this "patch" for Prima/Makefile.PL, because Prima::codecs::win32 ends up at unexpected place

sub setup_codecs
{
    # see if Prima::codecs:: is installed
    my ( $prereq, $have_binary_prereq);
    $prereq = 'win32' if $Win32 and not $cygwin;
    $prereq = 'win64' if $Win64 and not $cygwin;
    $prereq = 'os2'   if $OS2; 
    if ( $prereq) {
        print "Checking for Prima::codecs::$prereq... ";
        eval "use Prima::codecs::$prereq;";
        unless ( $@) {
            print "yes\n";
            $have_binary_prereq++;
            push @LIBPATH, qd("$Config{installsitearch}/Prima/codecs/$
+prereq/lib");
            push @INCPATH, qd("$Config{installsitearch}/Prima/codecs/$
+prereq/include");
            if( $prereq =~ /win32/ ){
                my $f = $INC{'Prima/codecs/win32.pm'};
                $f =~ s/.pm$//;
#~                 push @LIBPATH, qd("$f/lib");
#~                 push @INCPATH, qd("$f/include");
                $LIBPATH[-1]=qd("$f/lib");
                $INCPATH[-1]=qd("$f/include");
print "$_\n" for $f,@LIBPATH, @INCPATH ;
            }
        } else {
            print "no\n";
        }
    }

FWIW, Prima::codecs::win32, should have two class methods, INCPATH and LIBPATH which return the correct path
