You can't just copy Socket6.pm to different architectures, because it requires system-dependent C code to be compiled and installed. This applies to any perl module incorporating XS code.

You need either a system dependent distro for each OS, or you could possibly get around that by building every XS module for each system once, and compile them into a single bundle making sure that only the right file for the current OS is used. I'm not sure which one is easier.
