`make all' broken?

[Patrick McCarty]

Hi,

Compiling from scratch on latest master, I get this output:

  Compiling /home/pnorcks/git/lilypond/Documentation/out/fdl.texi...
  /home/pnorcks/git/lilypond/Documentation/out/fdl.texi is up to date.
  lilypond-book.py (GNU LilyPond) 2.13.12

                  -o ./out/colorado.html \
                  ./essay/colorado.bib

  bibtex: Not writing to /tmp/tmpSnvwo5bib2html.blg (openout_any = p).
  I couldn't open file name `/tmp/tmpSnvwo5bib2html.blg'
  Invoking `bibtex /tmp/tmpSnvwo5bib2html'
  make[1]: *** [out/engravingbib.itexi] Error 1
  rm out/weblinks.itexi
  make[1]: Leaving directory `/home/pnorcks/git/lilypond/Documentation'
  make: *** [all] Error 2


I assume this is related to the bibliography "hack".  Graham, do you
know what's wrong here?

Thanks,
Patrick
