[PD] Automatically add deken packages to path ?

[nik at parkellipsen.de]

Hi,

whenever installing a package with deken, I still have to add the path
manually for the extensions to be found. 

The base path is present, but the package paths are not.

Is this the expected behaviour ? If not, is there a setting 
so that the installed packages are found automatically ?

Best,
Niklas
