The good news is the package works if the target assertion at this line
is simply commented out. So the proper fix should be trivial. The bad
news is the target looks like it /should/ be perfectly valid and I
don't have enough rust clue to decipher where it goes wrong. It might
be a bug in the system-deps and/or cfg_expr crates.
