Hi Jelle, thanks for taking a look.

I'm sending a new patch after this message, but I'm replying to your review below.

I moved it to inputs now. But I placed it in native-inputs following the guile-build-system documentation in the manual:

"Packages built with ‘guile-build-system’ must provide a Guile package in their ‘native-inputs’ field."

Did I misunderstand or should that part of the manual be updated?

I added a new phase to set Guile load paths so that they take (getenv "GUILE_LOAD{,COMPILED}_PATH") into account, and modified the wrapping accordingly. In my test, running "guix shell --pure guile-proba -- proba run tests" works now.

I put building into a separate phase.

It was possible. Now it looks like this:
