what perl modules are installed

[Edwardson, Tony]

I use the following

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

foreach my $module (sort $inst->modules()) {
        printf "%-30s%s\n", $module, $inst->version($module);
}

Subject: what perl modules are installed

I am sure other people have had this requirement.

How do I find out what perl modules are installed on a system and what 
version?

I have started at a company that has several servers, supposedly all 
servers have the same
modules installed but in practice modules have been installed by a 
variety of means, directly
from cpan, by manual installation, by copying files from other servers. 
I need to be able to
get a list of what is installed on each system.

I have found reference to a file perllocal.pod which is supposed to 
contain the list of perl
modules and their date, but no version and I suspect it is only used 
when doing a 'make'.

Is there a quick way of doing this rather than traversing the @INC 
directories and reading
every file?
