In that case, simply install Socket::GetAddrInfo; it's backed by the same XS and PP code that was copied into core Perl at 5.14.0.

Also note that I'm in the process of making Socket dual-life, so you can install the current development version of that

This is known to work back at least as far as Perl 5.10.0, and hopefully soon this will reach a real 1.95 release. This will mean your code continues to work unchanged on later Perls too.
