Pratyekabuddhas actually manage it in a kalpa where no buddha has been born. They are not full buddhas, though, as they do have relatively limited compassion and are not omniscient.
The only requirement is that they hear the teachings of a buddha in one life. Since there will be no buddha in the kalpa he is reborn, he will not be a buddhist and will not be capable of spreading the dharma after reaching enlightenment. Even in a good kalpa like ours, I believe it's quite safe to assume that everyone has been a buddhist in one life or another, since we all have been in samsara for countless eons.
