Comment:
- which unix are you using ?
- do you have also downloaded data ?
$ ls data/sounds/ should contain 141 .wav
(in debian, the data are a separate pakage in non-free)

That looks like the developement branch of PhysicsFS. Last time I checked
lincity did not work with that one. Try a stable version.
