You can run 'ldd /path/to/fgfs'. fgfs must be the executable created by
g++, not a script. If you usually run fgfs using a script that modifies
LD_LIBRARY_PATH, the modifed LD_LIBRARY_PATH setting must be in effect
when you run ldd, otherwise the output won't show the exact libs fgfs
loads when run by the script. For instance, d&c.sh users can do:

  /path/to/run ldd /path/to/install/flightgear/bin/fgfs

(or use the 'run_ldd.sh' script, which is redundant with the more recent
and general 'run' script).
