New issue 2529 by address@hidden: configure should error for any  
missing software
http://code.google.com/p/lilypond/issues/detail?id=2529

IIRC right now configure with give a warning for any missing software for  
the doc build, and an error for any missing software required for building  
lilypond.

I think we should produce an error for any missing software at all,  
possibly adding a --ignore-missing-doc-build-requirement or  
--requirements-for-binaries-only option to produce warnings instead of  
errors in such case.  In this age of huge hard disks and widespread  
broadband internet, it's not worth playing coy trying to let people build  
lilypond without installing small packages like dblatex.
