The CPAN Tester's Module Author's FAQ provides a good suggestion. I was close but this is better:

"How can I indicate that my distribution only works on a particular operating system?"

While it isn't a very elegant solution, the recommend approach is to either die in the Makefile.PL or Build.PL (or BAIL_OUT in a test file) with one of the following messages: 

    No support for OS
    OS unsupported

CPAN Testers tools will look for one of those phrases and will send an NA (Not Available) report for that platform.
