podlators 4.02

Another day, another podlators release. This time, a slightly misguided cleanup I did on the build system broke useful installation for versions of Perl prior to 5.11. (The module would be installed, but in a directory shadowed by the Perl core library, so to no real effect.)

Thanks very much to Peter Rabbitson for all the help in sorting out these build issues. Now I have better comments about all the interesting traps for dual-life modules.
