Actually, (without knowing much about this whole process), it sounds like his ttsd binary is at /usr/local/ttsd. Removing it would likely stop it working at all. He probably needs to move /usr/local/ttsd to /usr/local/bin/ttsd, modify his startup to accomodate that move, then create the fifo.

But I could be totally wrong, as his startup seems to be referencing /bin/ttsd.
