Unable to build HEAD

I want to try out 8.0 and am trying to build it on a quad core Xenon
system.

I deleted the contents of /usr/obj and most of /usr/src, csup'ed '.',
and did a buildworld.

make: don't know how to make /usr/obj/usr/src/tmp/usr/lib/libcrypto.a. Stop
*** Error code 2

Any idea what is causing this?

make.conf has nothing except KERNCONF and Perl version lines.
make.src is:
WITHOUT_ATM="YES"
WITHOUT_GPIB="YES"
WITHOUT_I4B="YES"
WITHOUT_IPX="YES"
WITHOUT_LPR="YES"
WITHOUT_NCP=YES
WITHOUT_NIS=YES
WITHOUT_OPENSSH=YES
WITHOUT_PF=YES
WITHOUT_PROFILE=YES

I couldn't find anything like this in the archives. Has anyone seen
this? Any idea how to fix?
