Sorry about that.  We lost the ability to bootstrap from 4.08 in 6.2,
and didn't update the docs.

However, as Don pointed out, 6.2 can be bootstrapped from C sources
rather more easily than previous versions, so there's no need to start
from 4.08.  Follow the detailed instructions in the Building Guide, and
you should be fine.
