nioswiki instructions: buildroot fialed!

I followed the buildroot guide of "http://nioswiki.jot.com/WikiHome/OperatingSystems/BuildrootGuide".

Because i donot know where to download the old SNAPSHOT .I edited the build file as follows :

SNAPSHOT=20060506

The final message of the build is:

I donot know what has happened.

I test 'nios2-linux-uclibc-gcc -v',it's ok.

Then test 'nios2-linux-uclibc-flthdr ~/rootfs/bin/busybox',it tells cannot open busybox.

I found /rootfs/bin/ exists nothing.

I configured the kernel by 'make ARCH=nios2nommu CROSS_COMPILE=nios2-linux-uclibc- hwselect SYSPTF=your_system.ptf' and 'make ARCH=nios2nommu CROSS_COMPILE=nios2-linux-uclibc- menuconfig',it's ok.

But after executes "make ARCH=nios2nommu CROSS_COMPILE=nios2-linux-uclibc- zImage',it reports:
