[linux-audio-user] Building SpiralSynthModular - undefined libpng references

  What does 'whereis libpng.so' report ? I'm wondering if you have 
another libpng somewhere... Maybe you should  check for an old zlib too...

Best,

I've tried building 0.2.0rc2 instead of 0.2.1, but the result is the same.  I also tried not using the --enable-jack option when "./configure"ing, with no effect.
