Thanks for the clear explanation of the matter, IOhannes.

Why not simply recompile externals after fixing s_path? Pd-extended already
comes with most externals recompiled for every new release and adding legacy
stuff just creates more confusion in maintaining the source down the road.
In other words, FWIW and IMHO I think there is way too much effort the
community is trying to pour into binary compatibility for a system that
clearly begs for further enhancements in the core API.

Best wishes,
