how to install perl modules

One of the simplest ways to install Perl Modules, with ActiveState Perl Package Manager.

If you're lucky enough to host your Perl apps in a server without firewall and proxy constraints...
Just launch DOS and run ppm!
e.g.
c:\>ppm
ppm>install PAR-Packer
bla bla bla....
ppm>exit

If your server is residing behind a firewall or is using proxy, the most common problem you will see is "Could not locate a PPD file for package xxxX".
A simpler alternative (than consulting the network admin and setting proxy env vars) would be to:
Search for PPM packages at http://ppm4.activestate.com/ or numerous other repositories such as http://www.bribes.org/perl/ppmdir.html
Download the Perl module archive (tar.gz) and the .ppd file, and place them in a local directory. Make sure the path does not contain spaces.
Launch ppm from command line and set the repository to your local directory.
e.g.
c:\>ppm
ppm>set rep Local c:\perl\addon
ppm>set
ppm>install PAR-Packer

How to create exe from Perl files

Option 1: Use a Perl package such as PAR or PAR-Packer.
Assuming you have installed ActiveState ActivePerl, just go to command prompt and run the following:
ppm (launch perl package manager)
search (confirm the package available for download)
install

More info:
PAR-Packer: http://search.cpan.org/~rschupp/PAR-Packer-1.008/lib/pp.pm
example: pp -o packed.exe source.pl

Option 2: Use Perl2Exe.
http://www.indigostar.com/perl2exe.php
Download the version compatible with your Perl Installation and unzip the contents. Refer to the readme for more info.
Basically the command should just be perl2exe yourscriptname.pl

Option 3:
Use perlcc built-in command. I 'm not sure whether this works for Windows though.
