That's bizzare- I'm not sure how tts is working if you getting those messages. In any case you just need to put flite and sleep somewhere in your path- I put mine in /bin, although I guess /usr/local/bin is the "right" place. Note: I would suggest making a symbolic link to flite and put flite somewhere on your /drive0 since it's so large. (i.e. ln -s /drive0/roadmap/flite flite)
