I tried to install Pijul alpha 49 on Windows, but it fails when building libpijul

error[E0053]: method `set_permissions` has an incompatible type for trait

Thanks! I believe I’ve fixed this, and republished on crates.io

Yep that fixed it for me, but now it fails on a different error within Pijul itself.

Should I file a separate issue for this?

Just tested this on Windows, it works.
