You cannot always do this, especially not when going from 8.2 to head, because you need to build a toolchain first, which includes updated headers and other components. It's probably best to just run "make buildworld", which will take care of everything. Otherwise, run "make toolchain" first, followed by "make buildenv". In that build environment, you can just change to the lib/libc directory and run make. NOTE: Do *not* install the updated libc if you are running an old kernel, or you will most likely hose your system.
