use [declare -path] instead of [declare -stdpath]
With Pd-0.50, using e.g.
[declare -stdpath <libpath>] will not find externals that were downloaded via deken and installed in the suggested default installation (
~/Documents/Pd/extra or a similar atrocity).
instead the code should use
[declare -path <libpath>], which also searches /path/to/pd/extra (at least for newer versions of Pd).
if you want to make absolutely sure that the libraries are found regardless of Pd-version and installation-path, you might want to use both
-stdpath <libpath> -path <libpatch>.
