Newbie CPAN issue

Hello list,
	I recently was trying to mess around with CPAN and have seemed
to get myself into a bind.

System- OpenBSD 3.8

The are two scripts I was messing with:

List-modules.pl:
-------------------------------------------------
#!/usr/local/bin/perl

use ExtUtils::Installed;
my $instmod = ExtUtils::Installed->new();
foreach my $module ($instmod->modules()) {
my $version = $instmod->version($module) || "???";
       print "$module -- $version\n";
}

-------------------------------------------------
And

Remove-modules.pl:

-------------------------------------------------
#!/usr/local/bin/perl -w

use ExtUtils::Packlist;
use ExtUtils::Installed;

$ARGV[0] or die "Usage: $0 Module::Name\n";

my $mod = $ARGV[0]; 

my $inst = ExtUtils::Installed->new();

    foreach my $item (sort($inst->files($mod))) {
             print "removing $item\n";
             unlink $item;
          }

     my $packfile = $inst->packlist($mod)->packlist_file();
          print "removing $packfile\n";
          unlink $packfile;
-------------------------------------------------

On a default install:

# perl list-modules.pl
Perl -- 5.8.6

On the system I was messing with:

Can't locate Cwd.pm in @INC (@INC contains:
/usr/libdata/perl5/i386-openbsd/5.8.6
/usr/local/libdata/perl5/i386-openbsd/5.8.6 /usr/libdata/perl5
/usr/local/libdata/perl5 /usr/local/libdata/perl5/site_perl/i386-openbsd

As you can see I deleted the Cwd.pm module because I was trying to
remove all the modules I had added to get it back to the original state.

So...a couple of questions:

1. How do I fix Cwd.pm error?

2. Why did removing the Cwd.pm module kill cpan?

3. Once Cwd.pm is installed as a module can you remove it?  How do I
remove all modules I have installed to get it back to original state?

4.  All I wanted to do was install two modules: Digest::SHA1 and
MIME::Base64 and it kept complaining about bad cheksums.  Then I even
tried a cpan> install Bundle::CPAN and it returns:

"Distribution id = G/GB/GBARR/Bundle-libnet-1.00.tar.gz
    CPAN_USERID  GBARR (Graham Barr <[email protected]>)
    CONTAINSMODS
    MD5_STATUS
    localfile
/root/.cpan/sources/authors/id/G/GB/GBARR/Bundle-libnet-1.00.tar.gz

I'd recommend removing
/root/.cpan/sources/authors/id/G/GB/GBARR/Bundle-libnet-1.00.tar.gz. Its
MD5
checksum is incorrect. Maybe you have configured your 'urllist' with
a bad URL. Please check this array with 'o conf urllist', and
retry."

Thanks for the help.  I would prefer not to reinstall anything as this
is a production server.


Thanks,
