broken build of 2.16.2 (git 11cdcc31caf00b9b4931bcda846e14fdfddcfd41)

[Knut Petersen]

I tried to rebuild lilypond 2.16.2 (git 
11cdcc31caf00b9b4931bcda846e14fdfddcfd41), but make doc fails:


/home/knut/git/lily/build/scripts/build/out/run-and-check "cd ./out-www; texi2pdf -I ./out-www -I

/home/knut/git/lily/Documentation  essay.texi < /dev/null" "essay.texi2pdf.log"

Please check the logfile essay.texi2pdf.log for errors
