Error building world for -current

Hi,
I am running into a strange error when trying to build world for -current.

===> usr.bin/kdump (depend)
sh /usr/src/usr.bin/kdump/mkioctls /usr/obj/usr/src/tmp/usr/include >
ioctl.c
In file included from <stdin>:96:

Tried removing /usr/obj but still the same result.

Am I missing something here?
