Thanks grantm but this doesn't really give me what i'm looking for either. The closest i've got so far has been by comparing the modules to the html pages supplied by Activestate:

my $file;
my $module;
my @installed;
my %installed;
my @standard;
my %standard;
my @non_standard;
my @INC_html = @INC;

map {s/perl/perl\/html/i;} @INC_html;

# Find all '.html' suffixed files in paths contained in the array @INC
+_html
find( sub { push @standard, $File::Find::name if -f _ && /\.html$/ },@
+INC_html);
 
foreach $file (@standard)
{
$file =~ /(.*lib\/)(.*)(\.html)/;
$file = $2;
$file =~ s/\//::/g;
}

# Find all '.pm' suffixed files in paths contained in the array @INC
find( sub { push @installed, $File::Find::name if -f _ && /\.pm$/ },@I
+NC);
 
foreach $file (@installed)
{
$file =~ /(.*lib\/)(.*)(\.pm)/;
$file = $2;
$file =~ s/\//::/g;
}

# Build a look-up table (Hash) for the standard modules

@standard{@standard} = (1) x @standard;

# Look-up standard and non-standard modules

foreach $module (@installed)  
{
    unless(exists $standard{$module})
    {
        push @non_standard,$module;
    }
}

Unfortuantely ActiveState do not provide an html page for every module that they supply in the Perl bundle.

Looks like i may have to do a fresh install on another machine to get the unadulterated module listing.
