why are you using OSG 3.4.0? granted 3.2.0 is the minimum version but... i will recommend to try OSG 3.4.2... i switched from 3.4.0 to 3.4.2 with the download_and_compile script way back after it had cooked a bit and i've had no problems that i'm aware of... i've been building my own (PLIB, OSG, SimGear, FlightGear) since i found the d&c script...
but, back to your OSG 3.4.0... is this a self compiled version or a system installed one?
if self-compiled, are you sure that it is finding and using your installed png and ttf libraries?
do you have the -dev flavor of them installed?
what does "ldd fgfs" show?
what OS are you on again? i know linux since you're using .so files but which linux?
