Hi, I am trying to build pijul on Guix but when I compile libpijul I get these errors. At the same time there are quite understandable hints on how this can be solved. I tried to build with rust versions 1.60 and 1.67 the errors are the same. Should this be solved on the libpijul side?

Compiling libpijul v1.0.0-beta.4 (/tmp/guix-build-rust-libpijul-1.0.0-beta.4.drv-0/libpijul-1.0.0-beta.4)
