I believe the current naming convention for guile packages is:

* guile1.8-PACKAGE: for guile@1.8
* guile2.0-PACKAGE: for guile@2.0
* guile2.2-PACKAGE: for guile@2.2
* guile-PACKAGE: for guile@3.0

... though this is not always adhered to.  Basically, ‘we’ want to use
the latest version of guile by default.

So I would suggest:

A (preferred): replace guile-2.2 with guile-3.0 in 'inputs'.  But perhaps
  guile-cv does not (yet) support guile-3.0 (there have been a few incompatible
  2.2 -> 3.0 changes)
or
B: your patch, and rename guile-cv to guile2.2-cv.

Greetings,
Maxime.

I tested to build guile-cv with guile-3.0.  But guile-cv's test is
failed, so your suggesion A is not easy.

Therefore, I think suggesion B is better.

Best Regards,

I agree with Maxime that Guile 3.0 would be best, but in the meantime,
your patch looks like the right thing.

Applied, thanks!
