That sounds somewhat reasonable, but would it be possible to have the "regular" libsvm and the dense one on the system and dyn-link / build against both of them? That would solve the bundling issue on this. Is there any special version required?

Which version of liblinear did you bundle? So I can run some diff on pristine src and current (1.93) version. Thanks for the quick reply!
