(require 'rnrs/bytevectors)

ought to get the job done, but it does not. What I get is the error

Error: Could not locate library: rnrs/bytevectors

when (current-require-path) is the default

("lib/R6RS" "lib/SRFI" "lib/Ffi" "lib/Base" "lib/Standard" "lib"
"lib/Debugger" "lib/SLIB")

Can I do this without moving into ERR5RS mode? How?
