Hello,

I've attached the following patches looking for feedback on how to resolve the following error I get when running `./pre-inst-env guix build whatweb`.

#+begin_example

#+end_example

Also, I wasn't sure if bundler-audit should be named ruby-bundler-audit. The bundler package didn't start with 'ruby-' so I left it off for bundler-audit as well, but can change it if it's wrong.

Both 'bundler-audit' and 'ruby-ippaddr' can be built without issues.

Thanks,
Ryan Desfosses
