The p5-Paws port is quite old -- nearly four years out of date -- and is missing support for quite a few things, like IPv6.
Looks like there was a previous attempt in bug 223371 to do this, but it never happened.
^Triage: assignee timeout (> 1 year).
The patch in that bug report bumps the version to 0.44.
Feel free to apply it and install paws.
