looking for help debugging a "return code 1 error"

[Kieren MacMillan]

Hello all,

In 2.19.58, I’m getting a “return code 1” error for some reason, in an 
essentially blank score (though there are lots of include files, context 
tweaks, etc.).

Can anyone look at the following log output and tell me roughly what I should 
be looking for in order to fix this?
(n.b. Including a MWE is impossible; even sending a reasonably compact set of 
include files to someone offline would take some untangling work.)

Thanks,
Kieren.
