'Spinlock called when not threaded.'

[walt]

While trying to build openoffice.org-2 on -CURRENT:

gmake[4]: Leaving directory 
`/usr/ports/editors/openoffice.org-2.0/work/OOo_2.0.0rc3_src/moz/unxfbsd.pro/misc/build/mozilla/security/nss/cmd/shlibsign/mangle'

I cvsup'd and rebuilt everything as of this morning, 20051119.

Any ideas?
