above answers ++; but the question is NOT unambiguous. IMO, a plausible alternate meaning is:

"How can I obtain copies of __(name)_'s perl versions 5.n.n to 5.n+?"

as OP might conceivably be interested in testing compatibility.

Hint to OP: If this was your intent, update to mention your desired OS, any preference on (name) -- eg, ActiveState, Vanilla,....

Partial Answer: Some vendors/suppliers maintain availability of versions which were released prior to the current version. Check.
