As you can see, configure looks for guile 3.0, fails and falls back to guile 2.2, which it finds as /usr/bin/guile-2.2.

Gnutls provides guile bindings, but they are not necessarily built by your distribution. From my experiments with debian/hurd, the bindings were not present, so probably the same with debian/linux? You'll probably have to checkout gnutls and build the bindings.

The configure script only checks that the guile it found (your 2.2) can load the (gnutls) module, so there cannot be a version mismatch, unless debian built the gnutls module with guile 3.0. Check with your distribution what files are installed with the gnutls package. There should be some in /usr/lib/guile/.

You'll need to look at the dependencies, some of them are probably not provided by debian yet. I remember some discussions about creating a debian package of guix. If this was accepted, then the dependencies must be available at least in unstable. You might want to check.
