error: crate librocksdb_sys required to be available in rlib format, but was not found in this form

Per @BusyJay:

I occasionally run into error when make dev:

error: crate librocksdb_sys required to be available in rlib format, but was not found in this form

@brian Anderson Do you have any ideas?

My first guess is that this is a cargo pipelining bug, as it has only shown up recently and specifically happens with make (where pipelining is turned on). Reportedly the problem goes away by running make again, which also makes me think its likely a pipelining-related concurrency bug.

Similar report rust-lang/cargo#6993, closed as unreproducible.

Our current toolchain is nightly-2019-06-14. Probably worth doing an upgrade just as a stab-in-the-dark.

Yes, there was a fix (rust-lang/cargo#7008) which landed somewhere around 2019-06-18.
