Thank you for working on this, both upstream and the package itself.

I think guile should be a normal input.  Other packages like this
(e.g. guilescript, ccwl) seem to do it that way.

This seems almost correct, as it extends the GUILE_LOAD_{,COMPILED}_PATH
at runtime; the user would for still need to have the guile-config and
guile in their profile. Although guile-config is also listed as a
propagated input, when the guile search paths specifications are not
active, the following would not work:

`guix shell --pure guile-proba -- proba run tests'

You could have a look at the 'wrap phase of the ccwl package; they use
the value of (getenv "GUILE_LOAD_{,COMPILED}_PATH") retrieved while
building the package to wrap their script.

Nitpick, so feel free to ignore:
You could split up building and installing the manual.

All of the files listed in this regex are still installed in
<out>/share/guile/site/3.0.  Do you think it would be possible to ensure
these files are not installed?
