Search Paths issues

howdy, can Purr Data find externals in the standard path of Pd-Vanilla and extended? On Mac this is

/Library/Pd or ~/Library/Pd

I can see these folders are added as startup flags

but anyway, tried declare and calling a library from that standard path, no luck! Neither with slash declaration.

Moreover, I did add a path to a folder in ~/Library/Pd myself, it di work and I could call the externals...

I did apply, save and close... but when I restarted Purr Data, it wasn't there anymore :/
