Fatal error 'Spinlock called when not threaded' when trying toupgrade kdelibs-3.1.4 port

Hi,

It has been almost a month that my system fails to upgrade the 
kdelibs-3.1.4 port on my FreeBSD-current box. I have synchronized my OS 
with -current many times, but the problem seems to persist. Here is the 
error message:

../dcop/dcopidl/dcopidl ./ksycoca.h > ksycoca.kidl || ( rm -f 
ksycoca.kidl ; false )
Fatal error 'Spinlock called when not threaded.' at line 88 in file 
/usr/src/lib/libpthread/thread/thr_spinlock.c (errno = 0)
Abort trap (core dumped)


          If anyone knows what to do, please tell me. Thanks. Guillaume.
