make install: No rule to make target `index.hhk'



I don't try to do make install all that often, but when I do, the install seems to progress fairly far and then fails.  I do have a working hhc  available at my cygwin terminal.
I've done ./bootstrap, but  I'm not sure my  Starkit, TclKit, img.kit, gnuplot, and wxmaxima are installed correctly. I'm sure there are dozens of possibilities. Hints?

s: $bad_files" ; \
echo "Run /doc/info/fix_tab to fix the problem." )
