If I have a 64 bit cpu, do I need a 64 bit release of Perl?
No. Leastwise not on Windows or (those varieties of*) *nix I am aware of. The 64-bit versions of will also allow you to build and run 32-bit binaries.
(* there are so many vareties, there might be some that won't; who knows :)
Are there other factors in play?
Other factors that enable or prevent what?
A 32-bit binary will be limited to using 1 or 2 or 3GB of ram per process depending upon your OS and build parameters; regardless of how much is physical available. But the 32-bit Perl will use somewhat less memory for a given size of array or hash, because it only needs 4 bytes per pointer rather than 8.
