Log Message:
-----------
Make configure check the version of Perl we're building with, and reject
versions < 5.8. Also, if there's no Perl, emit a warning informing the
user that he won't be able to build from a CVS pull. This is exactly the
same treatment we give Bison and Perl, and for the same reasons.
