Congratulations, It works!

I had to do this first on my fedora box:

yum install fluidsynth-libs.i686
yum install jack-audio-connection-kit.i686

Loading a sound using the Class->Audio->SOUND object causes a segfault
for me though:

Error: Segmentation violation(11) [code 0] at 22527186
     {Offset 1852 inside #<Function (method om-draw-waveform
(soundpanel t)) 22526A4A>}

  3 (abort) Return to event loop.

Type :b for backtrace or :c <option number> to proceed.
Type :bug-form "<subject>" for a bug report template or :? for other options.
