Why would someone do something so selfish in a module contributed to CPAN?

Well, in an ideal world* yes. In the real world, no. I will fix the module, rendering the "class variables and methods" as actually belonging to the namespace, and suggest to the author that he shouldn't be pulling silly stunts like this.

For my immediate purposes, I'll simply override the methods as required in my subclass. I have a deadline to meet, since I write code for money rather than intellectual stimulation :)
