Can no longer build.

I have the following problem:

dak@lola:/usr/local/tmp/lilypond$ CPU_COUNT=9 make -j9
Making scripts/out/lilypond-invoke-editor.1 
help2man: can't get `--help' info from out/lilypond-invoke-editor

So how come my lilypond-invoke-editor script starts with

"echo no not found -s"

as its interpreter?  Note that some underlying problem might not be new:
I have frequently had to start make a second time here (I considered it
a timing problem): it may just be that previously the failure left an
empty file that allowed the next iteration to complete.
