I know and thanks for that, but I really want to avoid putting myself in  
those situations for now. It would be confortable for me to have an  
updated version of pd-ext just because I'm teaching myself about data-s,  
but it really doesn't stop me from working (or I would just bite the  
bullet). I prefer to wait than to start this tryout-and-fail game again  
(as you might understand from previous posts, I don't have much pacience  
for this anymore). this might even be a way to make me try ubuntu again  
[that is, until something in ubuntu fails without me causing it, as it  
happens sometimes].

anyway, I updated the wiki as much (or as little) as I could.
