cannot compile vmstat

Hello,
while compiling NetBSD-curent I run into this, details below.

Date:           Jan/03
System:         NetBSD 4.0_RC5
Platform:       macppc, PowerMac G4
Source code:    last cvs update made at 22:00 Jan/02 GMT
Command:
         ./build.sh -O ../obj.macppc -T ../tools -X ../xsrc -j3 -U -u -N 0 -x 
release

Output:
...
dependall ===> usr.bin/vmstat
In file included from /n4/usr/src/usr.bin/vmstat/vmstat.c:108:
/n4/usr/src/../obj.macppc/destdir.macppc/usr/include/nfs/nfsnode.h:44:27:
error: sys/workqueue.h: No such file or directory
nbmkdep: compile failed.
--- vmstat.d ---
*** [vmstat.d] Error code 1
1 error
nbmake: stopped in /n4/usr/src/usr.bin/vmstat
--- dependall-vmstat ---
*** [dependall-vmstat] Error code 2
1 error
nbmake: stopped in /n4/usr/src/usr.bin

Workaround:
manually copied sys/workqueue.h
to src/../obj.macppc/destdir.macppc/usr/include/nfs/.

Result:         compiled without problems
