It should work, I'm using it a lot. I use libportaudio.a, make 
sure you reference deimos/portaudio.di or have it in your 
`source` folder. Here's an excerpt from my dub.json (you might 
have to include other libs too):

"libs": [
         "portaudio",
         "asound",
         "jack",
         "sndfile",
         "FLAC",
         "vorbisenc",
         "vorbis",
         "ogg"
       ],

Also, compile or download the portaudio lib for x86_64, if you're 
on 64bit. Alternatively, compile your code with -m32.

BTW, did you pass the library to the compiler and linker?
