I have not tried installing that particular module from CPAN myself, but I have found it to be fairly easy to install modules directly from CPAN into ActivePerl.

Here's the steps:

• Use PPM to install mingw and dmake, which are available from the default ActiveState repository.
• If your system is behind a proxy, you'll need to add the http_proxy environment variable with the correct information to you Windows OS.
• Now, from a command prompt, you can install modules directly from CPAN by using syntax like cpan install Net::SSH2

Of course, it does look like that module you're interested in does require the libssh2 library to be installed first. Since I have not been through that process myself, I can't offer any pointers on how to get that library installed properly.

If you're not strictly tied to using ActivePerl 5.14, Strawberry Perl 5.12.3.0 does have a version of Net::SSH2 already included, which was mentioned in another response. Also, Strawberry Perl does have a preview release of 5.14. I'm assuming that Net::SSH2 would be included, but can't say for sure.
