Failure to compile against mdbook v0.4.32

I'm guessing this is related to the updated dependencies in 0.4.32.

To replicate:

cargo install mdbook mdbook-variables

Log:

Not sure of a workaround at the moment, trying to find the right combo of cargo install commands 😄 , but when I work it out I'll update this ticket.
