Akku commands print warnings from Guile

[rc-zb]

Describe the bug

Akku prints a series of warnings in the format of

WARNING: (guile-user): imported module (rnrs) overrides core binding `<something>'

each time its sub-commands get invoked.

Steps To Reproduce

Steps to reproduce the behavior:

1. nix profile install nixpkgs/nixos-unstable#akku
2. akku version (or akku --help or some other Akku commands; I haven't test them all, though)
3. the program prints

   ~ 
   ❯ akku version
   WARNING: (guile-user): imported module (rnrs) overrides core binding `newline'
   WARNING: (guile-user): imported module (rnrs) overrides core binding `display'
   WARNING: (guile-user): imported module (rnrs) overrides core binding `error'
   WARNING: (guile-user): imported module (rnrs) overrides core binding `read'
   WARNING: (guile-user): imported module (rnrs) overrides core binding `map'
   1.1.0

Expected behavior

If Akku works well, then it is insignificant what bindings are overrided by some modules, and the warning messages should be trimmed.

Yeah, akku works well enough to nixify its packages (akkuPackages attrset). I'll take a look at suppressing warnings in the next week. Thank you for reporting this!

So, there was a PR: https://gitlab.com/akkuscm/akku/-/merge_requests/7, merged Feb 8, 2021. We're using v1.1.0, released on Feb 6. I bumped akku to 1.1.0-unstable-2024-03-03, which removed the guile-user warnings, but not guile: warning: failed to install locale. Working on it

Oh, whoops, that's on my end. I didn't have the locale environment variables
