In zeek-4.0.3 (to which the port was recently updated from 4.0.2)
the header inclusion order has changed; the relevant diff:

 #ifdef __FreeBSD__
 #define OS_FREEBSD 1
-#include <sys/param.h>
 #include <sys/cpuset.h>
+#include <sys/param.h>
 #include <unistd.h>
 #else
 #define OS_FREEBSD 0

- sys/cpuset.h requires sys/types.h to define cpusetid_t (and friends),
- sys/params.h includes sys/types.h

  this is documented in cpuset(2)

This works on stable versions such as FreeBSD 13.0 w/ clang 11.0.1, though.
This is seemingly due to a header pollution fixed in llvmorg-12 import.
Before that, sys/types were included indirectly with #include <random>:
random -> istream -> ostream -> locale -> nl_types.h -> sys/types.h
With llvmorg-12 import, istream / ostream are replaced with iosfwd.
