with pd devel 0.38 from cvs and your externals from cvs on linux ubuntu i managed to compile dyn, py without any problem but when i try to load them into Pd i get: load_objet: Symbol "py_setup" not found or load_objet: Symbol "dyn_tilde_setup" not found
matju reported some problems when loading externals on devel_0_38 ... looks similar to me ...
still, i never experienced it, nor do i have any _detailed_ description of this problem ...
please send us a precise description of your setup ... especially, if you are loading any specific externals in advance ...
thanks ... tim
