Gipify update

This is an addon to the pull request to gipify.  I had to add these linker instructions, running node v0.10.0, on a Centos 5.2 machine.  Before I added the linker bits, I was getting the following from 'npm install .' of the previous pull request:

dswift@bunkhouse ~/node_modules/winston-graylog2/node_modules/compress-buffer$ npm install .
