I have 1.622 and there is a 1.636 available.

Latest available on CPAN is 1.643. Have you tried it ?

Other than that, the first thing is to find out why all of those scripts croaked. (It's likely the same or very similar reason for all of the failures.)
I would cd to the build directory and run perl -Mblib t/01basics.t and see what that throws up. Hopefully it will show some diagnostics that help explain what's going on.
Those same diagnostics would probably have also shown up during the 'make test' phase - so you could look there, too, if you still have that output.

Cheers,
Rob
