Sorry for the long delay! I made a couple of changes: I added python-abjad as a deprecated package, so it won't break for anyone who already has it installed. I sorted python-ply alphabetically when moving it to propagated-inputs. I also moved lilypond to inputs and removed the now unnecessary 'patch-source phase. Thanks! Patches pushed. -- Efraim Flashner אפרים פלשנר GPG key = A28B F40C 3E55 1372 662D 14F7 41AA E7DC CA3D 8351 Confidentiality cannot be guaranteed on emails sent or received unencrypted
