you need to either:

1) enable static overlays only; I guess ppolicy is only dynamic, so it
does not compile if dynamic modules are not enabled.

2) --enable-modules so that whatever run-time loading mechanism is
available on your platform (if any) is used, and ppolicy can be compiled.

In some sense, it looks like a configuration bug, since the dependency of
--enable-overlays with --enable-modules for those overlays that can only
be built as run-time loadable is not detected.
It's up to you to decide whether you better live with all existing
overlays built (--enable-overlays) but with --enable-modules as well, or
if you prefer to build only what's strictly required (e.g. chain overlay
staticlaly built into slapd).
