How am I wrongly using Math::BigInt?

[Paul Bennett]

So, I've got this Perl module,  
http://search.cpan.org/~pwbennett/Net-IPAddress-Util/lib/Net/IPAddress/Util.pm,  
and it's not-quite-randomly failing its test suite on not-quite-random  
platforms.

The testing summary is at  
http://matrix.cpantesters.org/?dist=Net-IPAddress-Util%200.10

As you'll be able to tell (with some digging), the tests that are failing  
are one or more of the tests named <code>/01-try-.*/</code>. These tests  
are all sanity-checks put in place to test the underlying modules and/or  
libraries that my module itself actually relies on. Those tests don't even  
<code>use</code> my module -- they run directly on the underlying modules.

Now, I know for sure that the libraries themselves can't possibly be  
broken: they're used by gazillions of people all day every day, even for  
"real" comp sci problems. I'm pretty sure the Perl modules that use the  
libraries aren't broken: they also seem to be used by other people all day  
every day.

So, after eliminating the impossible, what remains is that I'm misreading  
the docs badly enough that even my trivial "are you alive?" tests are  
written badly enough that they're crashing hard.

Is anyone here ready, willing, and able to help me figure out what I'm  
doing wrong?
