For chromaprint support in grilo-plugins the actual gst-plugins-bad chromaprint plugin is needed (not currently in portage). The build fails otherwise with USE=chromaprint.
It should depend gst-plugins-chromaprint (not in portage).

media-plugins/grilo-plugins: depend on gst-plugins-chromaprint for masked USE
gst-plugins-chromaprint is now packaged, so depend on it correctly.
However it remains package.use.masked for the time being.
Package-Manager: Portage-2.3.40, Repoman-2.3.9

This is now available in ~arch, but we still need to sort out availability for stable tree

Seems like a separate issue from this one.
