latest 5.2-current buildworld error

[Bin Ren]

Hi,

I tried to 'make buildworld' with latest 5.2-current. It ends with an 
error: ------------------------------------------------ echo cvs: 
/usr/obj/usr/src/i386/usr/lib/libc.a

error ---------------------------

And my '/etc/make.conf' is:
-----------------------------
PERL_VER=5.6.1
PERL_VERSION=5.6.1
PERL_ARCH=mach
NOPERL=yo
NO_PERL=yo
NO_PERL_WRAPPER=yo
CPUTYPE?=i686
CFLAGS= -O -pipe
CXXFLAGS+= -fmemoize-lookups -fsave-memoized
COPTFLAGS= -O -pipe
NOPROFILE= true
------------------------------

Maybe my make.conf has some troublesome option,
say CPUTYPE?

Thanks for all your help.
