core/sample.nim(52, 19) Error: undeclared identifier: 'SF_INSTRUMENT'

Hi, I get the aforementioned error when trying to compile on Ubuntu 14.04 32 bit.

I have libsndfile1-dev installed and have performed a nimble install on the nim's sndfile lib.

I'm a complete noob in regards to nim, so that doesn't probably help either.

Any Ideas?

Thanks!
