i'm constantly getting this same error every time i try make build...

i used cvs and got -current not long ago... maybe 2 weeks ago on a friday... anyway... i was experiencing a lock up problem... if i typed 'md5 &' as any user, it would just lock the system solid... so i figured i should re-cvs and get newer source to see if that fixes the problem... so i ran a cvs update... and it finished... then i did cd /usr/src and ran make build... it naturally runs make cleandir and gets all the way to a certain spot each time and dies... i changed nothing since the last make build.... (other than setting USE_NEW_TOOLCHAIN=no in /etc/mk.conf) ...

here are the contents of my /etc/mk.conf

OBJMACHINE=yes
MKOBJDIRS=yes
TOOLDIR=/usr/tools
USE_NEW_TOOLCHAIN=no

and the error i get is this...
