>Description:
CVSUP'ed 6.1 Release on 12 May 2006 with CVS tag RELENG_6_1
make -j6 buildworld:  completed fine
created new KERNCONF from new GENERIC from the CVSUP run
http://www2.cwrl.utexas.edu/SYVERSON is a listing of the KERNCONF
make -j4 buildkernel KERNCONF=SYVERSON:  Failed with the following errors

>How-To-Repeat:
simply attempt to build a kernel with make buildkernel on an AMD64 machine.

Fails in zlib module every time at the same place.
