bytevector-ref is missing as well.

For whatever reason, those procedures were not exported from lib/R6RS/larceny/r7r6.sld.

Well, the reason those procedures aren't exported by r7r6.sld is that they aren't exported by any of the R7RS or R6RS libraries. In R7RS and R6RS, their correct names are bytevector-u8-ref and bytevector-u8-set!.
