After running 'make linux-alsa' things run smoothly until:

My googling found no similar errors. Versions of dependencies are as follows:

alsa-lib 1.0.27.2-1

alsa-utils 1.0.27.2-1

libsndfile 1.0.25-3

gcc 4.8.2-5

flex 2.5.37-1

bison 3.0.1-1

make 4.0-1

I'm new to building software from source so I apologize if this is a beginner's misunderstanding. Thanks for any help you can give me; I'm looking forward to trying ChucK.
