Problem with usb4bsd rev566

[Stefan Lambrev]

Greetings,

Any idea why I get this error when trying go build kernel with latest 
usb4bsd?

I'm using FreeBSD 7.0-RC1 #11: Mon Jan  7 11:31:53 EET 2008 i386 and 
revision 566 of usb4bsd.
Is the new revision of usb4bsd only for -current or should work with 
releng_7_0 ?
