build failure

[Michael D. Godfrey]

As of the most recent updates I get
(on Fedora FC11 x86_64)

rm -rf octave.htp
if /bin/sh /home/godfrey/mdg/software/octave/devel/hg/octave/missing 
--run makeinfo --html -I.. -I. -I./..  -I . \
     -o octave.htp octave.texi; \
    then \
      rm -rf octave.html; \
      if test ! -d octave.htp && test -d octave; then \
        mv octave octave.html; else mv octave.htp octave.html; fi; \
    else \
      if test ! -d octave.htp && test -d octave; then \
        rm -rf octave; else rm -Rf octave.htp octave.html; fi; \
      exit 1; \
    fi

================================================
Followed by lots more error messages.  Using make -i I can get
the build to complete, and make -i check  produces more errors and
then runs the tests and reports the expected results.  So, something
is broken in the build of the doc/...

Is more detail needed?
