Answer 1

First, that distribution is called IO::Tty (which contains an IO::Pty module).

You seem to be missing some header files for a C library your module is linking to. You would have to install the headers beforehand. However… ioctl is Unix-specific and a part of the operating system. It is also notoriously unportable.

I could not find any reports of a IO::Tty install working on Windows, so it seems you can't use that module on Windows (without a Cygwin environment). As it happens this is also what the IO::Tty documentation says:

Windows is now supported, but ONLY under the Cygwin environment, see http://sources.redhat.com/cygwin/.
