Is anyone else having a problem building world with current?

I have not been able to build world for a couple of days with current.  
  I get to wpa and it breaks.

/wpa//src/utils -DCONFIG_CTRL_IFACE -DCONFIG_CTRL_IFACE_UNIX  
/usr/src/usr.sbin/wpa/wpa_cli/../../../contrib/wpa//wpa_supplicant/wpa_cli.c  
/usr/src/usr.sbin/wpa/wpa_cli/../../../contrib/wpa!
  //src/common/wpa_ctrl.c  
/usr/src/usr.sbin/wpa/wpa_cli/../../../contrib/wpa//src/utils/os_unix.c
echo wpa_cli: /usr/obj/usr/src/tmp/usr/lib/libc.a  >> .depend
===> usr.sbin/wpa/wpa_passphrase (depend)
make: don't know how to make wpa_passphrase.c. Stop
*** Error code 2

I am concerned because I haven't seen anything on the list.

thanks,

ed
