i'm contributing the the Crypt::GCrypt perl bindings for libgcrypt. Certain old versions of libgcrypt are simply buggy, and will guarantee a test suite failure for the perl module. I'd like to refuse module compilation entirely when those versions are present (and print a helpful error message explaining why users should upgrade). What's the best way to do that?

I have a very simple C program written that could be compiled with the same flags used by the translated GCrypt.xs; It returns a 1 for "bad version" or 0 for "good version".

Is there a standard way to have the perl Makefile.PL step build and run this program before emitting a Makefile? Or should i look at some other way to check this information? Or should i just let the test suites fail without any other checking?
