With same set-up (Ubuntu 14.04, gregorio version 4.0.0-release-4.0-1cc71cd-1) I can confirm an error if luaotfload is updated from 35328 -> 39093.
The message (with my test file) is: (./PrefDialog-4_0_0.gtex [... various warnings about deprecated commands] ! Undefined control sequence. <argument> \gre@font@music \GreCPPesOneNothing l.33 } % Reverting to luaotfload 35328 gets rid of the error.

Undefined control sequence. <argument> \gre@font@music \GreCPPesThreeNothing l.13 } % ? Since I didn't change anything in my installation ("Vanilla" TeXLIve 2015 on 64bit Ubuntu 14.04 LTS, all with latest updates ) e xcept above TL updates, it 's hard to believe the reason should be a general PATH or config error, rather, it seems gregoriotex might perhaps not be prepared for some of the most recent lua-related changes (?). Also complete new gregorio 4.0.0 install, rebuilding all formats, even today's luaotfload update [Tue Dec 15 17:41:10 2015] update: luaotfload (39078 -> 39093) did not help. Interesting side observation: gregorio 3.0.3 'survived' TeXLive 2015 updates in good shape. Anybody out there running gregorio 4.0.0 on a Linux system with latest TeXLive 2015 updates? Any idea of what might cause the trouble ?
