Yeah, I'm not quite sure how to do it better than that ... I think  
it's good enough for now. Maybe Ian will refine it when moving to the  
trunk :)

I discussed this with Marco P. G. on IRC. He had an issue with adding  
this as a prerequisite for each Sugar developer. To which I replied  
that IMO every Sugar developer should be able to rely on certain  
media libraries. Which he found okay for ogg vorbis, but maybe not  
for speex. Speex already is on the OLPC, but that may be by accident.  
There is no definitive list of what the platform will support. Worse,  
there is no such list at all. Maybe a post to Sugar list would be in  
order ...
