I found this alternative:
https://github.com/pitzer/SiftGPU

But not sure what to do with it?

[g-mac]

unzip it, call the directory "SiftGPU" instead of "SiftGPU-master" (if applicable), zip it again, call it sift_gpu.zip. insert in the repository before you run the script. that did the job for me..
