Don't.

Doing your own prompting and reading from STDIN is bad practice. Instead use ExtUtils::MakeMaker's prompt() subroutine. It will cope properly with things like buffering when CPAN.pm's output is being piped to tee(1) or if it is being driven by Expect, and with the user setting PERL_MM_USE_DEFAULT.
