I've gotten word back from the latest reporter of this problem that the newly tarred file (in 'gnu' format) fixes the problem. I'll be getting a release out with the correct tar format in the next day or so.
Unfortunately, the latest reporter of this problem said that he's seeing the same problem on other packages, so apparently there are other packages being sent out with the 'posix' format which are potentially going to affect CPAN users, so this might be a more serious problem. If there is somewhere that would be appropriate to document this behavior, that would be good to know.
