pth breaks gnome build

[Martin Smith]

Building gnome on a current (as of last weekend) system, it breaks at the
following point:
./libtool --mode=link --quiet cc -o libpth.la pth_debug.lo pth_ring.lo
pth_pqueue.lo pth_time.lo pth_errno.lo pth_mctx.lo  pth_uctx.lo pth_tcb.lo
pth_sched.lo pth_attr.lo pth_lib.lo pth_event.lo  pth_data.lo pth_clean.lo
pth_cancel.lo pth_msg.lo pth_sync.lo pth_fork.lo  pth_util.lo pth_high.lo
pth_syscall.lo pth_ext.lo pth_compat.lo pth_string.lo  -rpath
/usr/local/lib/pth -version-info `./shtool version -lc -dlibtool
pth_vers.c`
./libtool --mode=compile --quiet cc -c -I. -O2 -pipe -fno-strict-aliasing
pthread.c
In file included from pth_p.h.in:37,
                 from pthread.c:43:

is there a fix for this, I have done all the usual make delete-old etc and
hal has built ok, but I cannot get past this point.
Or alternatively is there a way I can skip it?
