The title does say "...for Windows". But I'm currently using the "TheKev" version in Debian Linux. You can try this guide:
http://vertcoin.org/gpu-miner-build-howto.html

Just substitute the URL for the miner:
git clone https://github.com/thekev/vertminer-gpu
instead of:
git clone https://github.com/Bufius/vertminer-gpu
