no tgen file in .shadow/bin/

[Andrea]

i'm trying to run tor using shadow shadow.config.xml > log, but i'm quite sure it's not working because i'm getting an error inside the log file saying: "Shadow XML parsing error 5: attribute 'path': '/home/me/.shadow/bin/tgen' is not a valid path to an existing regular file". I've followed the quick auto setup to install the tor plugin and i've got no errors, but inside .shadow/bin there's no tgen file
