It appears that this hasn't actually been resolved. i.e. after grabbing the current sid source (and an ldd on the current libgv-guile .so also indicates it's still built against 2.0):
$ rgrep guile | grep -F 2.0 debian/control: guile-2.0-dev, debian/control: This package contains the guile (2.0) bindings. debian/changelog: * Build using guile-2.0. Closes: #746012. debian/changelog: - Build using guile-2.0. debian/changelog: * Build using guile-2.0. configure.ac: [guile-2.0 >= "$GUILE_VERSION_MAJOR.$GUILE_VERSION_MINOR"], .pc/build_with_libann.patch/configure.ac: [guile-2.0 >= "$GUILE_VERSION_MAJOR.$GUILE_VERSION_MINOR"], .pc/versioned-plugin-config-file.diff/configure.ac: [guile-2.0 >= "$GUILE_VERSION_MAJOR.$GUILE_VERSION_MINOR"], .pc/50_remove_changelog_in/configure.ac: [guile-2.0 >= "$GUILE_VERSION_MAJOR.$GUILE_VERSION_MINOR"], .pc/ruby-config.diff/configure.ac: [guile-2.0 >= "$GUILE_VERSION_MAJOR.$GUILE_VERSION_MINOR"], Oh, and if feasible, please consider migrating directly to guile-3.0 instead.
