Dear Mr. Burlison

I'm a using Perl5.6 on WinNT and Linux.
ExtUtils​::Installed works fine on Linux, does not work on WinNT.

I found that error occurs on these lines​:
<quote>
  $module =~ s!$Config{archlib}/auto/(.*)/.packlist!$1!s;
  $module =~ s!$Config{sitearch}/auto/(.*)/.packlist!$1!s;
</quote>

I think that backslash(es) contained in $Config{archlib} and
$Config{sitesearch} occurs error.So I change these lines like
below and it works fine​:
<quote>
# $module =~ s!$Config{archlib}/auto/(.*)/.packlist!$1!s;
# $module =~ s!$Config{sitearch}/auto/(.*)/.packlist!$1!s;
#---Modify---------
  my $sCfg = $Config{archlib};
  $sCfg =~ s/\\/\\\\/g;
  $module =~ s!$sCfg/auto/(.*)/.packlist!$1!s;
  my $sCfg = $Config{sitearch};
  $sCfg =~ s/\\/\\\\/g;
  $module =~ s!$sCfg/auto/(.*)/.packlist!$1!s;
#---Modify---------
</quote>

I hope this may be your help.

Sinceryly.

Is this the "correct" patch​:
