While it's often the case that you can leave our steps when building -current from source, it is sometimes ABSOLUTELY REQUIRED that you followed the steps precisely.
This is one of those times. If you build a -current kernel without running config(8) and "make clean", then the resulting kernel WILL NOT RUN YOUR INSTALLED USERLAND. If that happens, you will have to boot from the old kernel (do you know how?) or boot from an alternate device like a CD. If you are not 100% comfortable with doing that recovery, then you should wait and install the next snapshot instead.
