I have made this change in a new=20 definition which inherits grep and told my pulseaudio-equalizer=20 package to use that as a propagated input, and that causes the=20 error to go away. For the sake of completeness, here=E2=80=99s the=20 definition I used: (define grep-fixed (package (inherit grep) (inputs (list pcre2)))) Best wishes, Matt 1. https://github.com/pulseaudio-equalizer-ladspa/equalizer
