On FreeBSD, kqueue is defined in sys/event.h . Yes, the wscript checked the availability of event.h, but failed with following errors:
./build/config.log:Checking for header sys/event.h
./build/config.log:#include <sys/event.h>
./build/config.log:/usr/include/sys/event.h:58:2: error: unknown type name 'uintptr_t'
./build/config.log:/usr/include/sys/event.h:60:2: error: unknown type name 'u_short'
./build/config.log:/usr/include/sys/event.h:61:2: error: unknown type name 'u_int'
./build/config.log:/usr/include/sys/event.h:62:2: error: unknown type name 'intptr_t'

This is because event.h requires sys/types.h and sys/time.h The C program generated by wscript does not included that.

It looks as though a patch for this issue was offered here:

. . . but the wscript portion was not applied. I just built from FreeBSD ports with the following portion of the first patch from that discussion, and that appears to have done the trick.
