I think in the Python world, in > requirements files it would be something like `library[specialization] > == version`, to install that variant. You can think of guile-dbd-* as plugins for guile-dbi. So, you install guile-dbi along with whatever plugins you want for guile-dbi. It's no different from installing emacs and installing emacs packages of interest. I don't think we need a special Guix feature for this. But, guile-dbi should be fixed to produce a proper error message that a required plugin is missing. It should not produce misleading error messages like "file not found". If you're up for it, you can try reporting this to guile-dbi upstream. Cheers! Arun
