I was able to build it after adding this

export TORCH_NVCC_FLAGS="-D__CUDA_NO_HALF_OPERATORS__"

per 

https://github.com/torch/torch7/issues/1086

When I try to run it I get errors that Lua packages are missing (probably
due to my path variables). I have a vague recollection that Simon and I
halped you once with this thing in the past. IIRC it was very picky about
the version of some Lua package and required their version not the one 
which comes with yum . 

Anyhow I am forwarding this to users at autonlab in hope somebody is using
it and might be of more help. Please stop by NSH 3119 and let us try to 
debug this.
