As JJC already indicated, your environment is "polluted". The fluidsynth 2.1.0 binary tries to use the libfluidsynth 2.0.2 . This cannot work. Execute ldd ./fluidsynth to see which libfluidsynth is being loaded. Then remove it as well as other fluidsynth leftover installation files (e.g. headers). Make a clean rebuild of fluidsynth 2.1.0, install it and try again.
