Persisten buildworld errors

All,

I've not been able to get a clean buildworld since after August 6th. The 
errors have varied (there was a persistent gcc error about various headers 
missing) and the latest problem is this -

c++ -O -pipe -I/usr/obj/cfs/bongo/current-src/src/i386/legacy/usr/include -I/cfs/bongo/current-src/src/gnu/usr.bin/gperf/../../../contrib/gperf/lib -I/cfs/bongo/current-src/src/gnu/usr.bin/gperf -c /cfs/bongo/current-src/src/gnu/usr.bin/gperf/../../../contrib/gperf/src/new.cc
/cfs/bongo/current-src/src/gnu/usr.bin/gperf/../../../contrib/gperf/src/new.cc:38: error: `operator new' takes type `size_t' (`unsigned int') as first parameter
