I am on 10.7 Lion and see about the same:

I suppose we have a too old version of cargo or with a feature not enabled? Does this come from a too old version of rust?

[ryandesign (Ryan Carsten Schmidt)]

The older version of rust that MacPorts makes available on these old systems does not have the "edition2024" feature that this software requires.
