The same for me (Arch Linux as well).  Unhappily, as you can see at
<https://projects.archlinux.org/svntogit/packages.git/tree/trunk/PKGBUILD?h=packages/gnutls>
gnutls is built without guile support (./configure … --disable-guile).
Thus gnutls from Arch Linux wouldn't work; so I installed gnutls using
guix and augmented guile paths with:

  /home/<user>/.guix-profile/share/guile/site

With this guile can find (gnutls) module and the error disappears.

Thanks for the explanation.  The manual is absolutely clear, I just
didn't read it properly :-)

Yes, I installed gnutls, but it didn't work because I didn't set the
right guile paths: “guix package --search-paths” recommends
"/usr/local/var/guix/profiles/per-user/<user>/guix-profile/share/guile/site/2.0"
but "gnutls.scm" is actually placed in
"/usr/local/var/guix/profiles/per-user/<user>/guix-profile/share/guile/site"
so ‘(use-modules (gnutls))’ failed for me.

Perhaps “guix package --search-paths” should be adjusted to recommend
the following (?):

export 
GUILE_LOAD_PATH="<path/to/guix-profile>/share/guile/site/2.0:<path/to/guix-profile>/share/guile/site"
export 
GUILE_LOAD_COMPILED_PATH="<path/to/guix-profile>/share/guile/site/2.0:<path/to/guix-profile>/share/guile/site"
