These troubles are recieved and understood by me and still wonder 
me since amarok (these days ) needs a special mysql to be compiled against and 
afaik mysql is approx. bigger than a python library that you need to drag in 
for the bindings.

JSmoke is therefore another attempt for Js on KDE?

Yes there is a kross binding for QtScript and there is a binding for KJS which 
confused me in the first place since its kind of a duplicated effort. 
A good question  coming to my mind is will we ditch KJS and build KDE bindings 
upon QtScript like you built KDE upon Qt or will we have kjs and keep it and 
try to fix it "at some point"?
Is there anyway to either fix KJS or Replace it with possibly JSmoke?
