portupgrade confusion

[Per olof Ljungmark]

Hi,
Running portupgrade on RELENG_7, got this whlie updating net-snmp and I 
have no idea what what this means. System ran -CURRENT from Jan 16 
before upgrade to todays sources (RELENG_7):

pkgdb -F
Fatal error F'aThread is not system scope.
t'a la etr rloirn e' Thread is not system scope.
3'1 6a ti nl ifniel e3 1/usr/src/lib/libpthread/thread/thr_sig.c6  (ienr 
rfniol e=  /usr/src/lib/libpthread/thread/thr_sig.c2 )(
errno = 2)
Abort (core dumped)

Thanks,

Per olof
