This is because the ‘build-things’ RPC would always use the new
protocol, even when talking to old daemons.

Fixed in 2734cbb.

Thanks, and sorry for the confusion!

Since updating my guix client (but not yet my server) to include the
recent commits related to the protocol update, I'm seeing these errors
non-deterministically while building things.  Retrying usually results
in success.

mhw <at> jojen:~/guix$ guix build -K openssl --cores=1
substitute: updating list of substitutes from 'http://hydra.gnu.org'... 100.0%
The following derivation will be built:
   /gnu/store/5hzf27bgygjp5ah3bfy8m0aa93yazgk3-openssl-1.0.2e.drv
guix build: error: build failed: EOF expected (protocol error?)
