it also evaluates on the *master*, not the agent, so you won't have any
luck with that.

Tricky. I guess the canon approach would be to write a custom fact that
retrieves the value for you after puppet has completed the setup on your
agent. During the next agent run, the cron can be generated using the
information from the fact.
The manifest should look like this:
if $myvalue {
cron { "mycron": command => "/some/thing/with $myvalue ...", ... }
}
so that the cron will only be created once the fact is indeed available.
