Build fails with node v4.1.2

[aratcliffe]

Hi, I'm attempting to build on OS X 10.10.5 with node v4.1.2 and the build is failing when attempting to build the node-srs dependency:

npm ERR! Darwin 14.5.0
npm ERR! argv "/usr/local/bin/node" "/usr/local/bin/npm" "install"
npm ERR! node v4.1.2
npm ERR! npm  v2.14.4
npm ERR! code ELIFECYCLE

npm ERR! srs@0.4.9 install: `node-pre-gyp install --fallback-to-build`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the srs@0.4.9 install script 'node-pre-gyp install --fallback-to-build'.

How can I resolve this issue?
