http://code.google.com/p/lilypond/issues/detail?id=2445

define-event-class has been removed.  It tampered with global variables and  
was unsuitable for multi-file runs.  See  
input/regression/scheme-text-spanner.ly for how to do this now.  This is  
actually a rather ad-hoc fix done instead of removing scheme-text-spanner  
altogether: the interface just builds upon somewhat sanitized internals,  
but the overall quality is not such that this would be dependable and/or  
cast in stone.  It is still at a "meddling with internals" level of code  
quality, and thus not guaranteed to stick around and/or be supported by  
convert-ly.

Yes, this is not really satisfactory.  But it will take some other work  
first before I can make progress here.
