This was posted last year but I found a need for it today. I had trouble running the script as it was. I had change the ppm to ppm3 and change the word repository to rep. This is a very useful script thanks for writing it.

#updateWorkingRepositories.pl
use strict;
use warnings;
use PPM::Repositories;
use Net::Ping;

remove_non_active_state_repositories();
add_repositories();

#remove all repositories, except the repositories that come installed 
+by default with 

ActiveState.
sub remove_non_active_state_repositories {
    
    my @repositories;
    <b>my $result = `ppm3 rep`;</b>
    for (split /[\r\n]/, $result) {
        #parsing lines that looks like 
        #[ 3] jenda
        my ($number, $repository) = $_ =~ /(\[[^>]*\]\s)(.*)/;
        if ($repository) {
            unless ($repository =~ /activestate/i) {
[download]

print `ppm3 rep delete

$repository` unless (/activestate/i); }        
        }
    }
}

sub add_repositories {
    for ( keys %Repositories )
    {
        my $repository = $_;
        my $location = $Repositories{$_}->{location};
        my $domain = trim_domain($location);
    
        my $p = Net::Ping->new('icmp');
        if ( $p->ping($domain) ) {
            print "$repository is alive.\n";
[download]

print `ppm3 rep add $repository $location` . "\n\n";

        } else {
            print "$repository is dead.\n";
        }
    }
}

#function that trims a domain
sub trim_domain {
    $_ = my $original_input = shift;
    $_ =~ s/^\s+//; #strip spaces at start of string
    $_ =~ s/\s+$//; #strip spaces at end of string
    $_ =~ s|^http://||; # strip http:// at begining
    $_ =~ s|/.*$||; # strip everything after the first /
    my $trimmed_domain = $_;
    
    unless ($trimmed_domain) {
        logMessage("trim_domain had a problem trimming $original_input
+");
        carp ("trim_domain had a problem trimming $original_input");
        $trimmed_domain = "$original_input couldn't be trimmed in trim
+_domain";
    } 
    return $trimmed_domain;    
}
