The cca related errors are fine and not fatal. Make sure you also have
the fluidsynth-dev package as well, or Swami won't see FluidSynth.

Those errors are also ok. The warnings are due to FluidSynth being run
non-root, which leads to higher system latency, which causes clicks if
the audio buffer is too small. Increasing the size of the audio buffer
will get rid of clicks at the cost of higher latency response.

Looks like everything is ok, except for the last error. FluidSynth is
trying to start up in ALSA mode, which apparently you aren't using ALSA
or FluidSynth can't find a valid configuration for using ALSA. If you
are not using ALSA (and instead OSS) you can start up swami with the
'-d' switch to disable plugins, then go into preferences and set the
audio driver for FluidSynth to OSS. Exit Swami to save the config file,
then re-start it without the -d switch.

I hope that helped :) Let me know if you are still having troubles.
