To be more constructive:
Maybe all commands could have a check counterpart added to the
dependencies, so as to fail gracefully only if needed, something like:
.check_XXX: if type -p $(XXX) > /dev/null ; then touch $@ ; else \ echo "command $(XXX) not found"; exit 1 ;
\ fi
foo: .check_XXX $(XXX) ...
I'm not sure how to check for the docbook style availability though.
