invalid data for nn scm-1

[hitxin]

when i run the sample in readme. th -i main.lua -dset text8 -name lstm_sm -nhid 100 -batchsz 32 -eta 0.05 -blen 20 -bfreq 5. I got this error.
torch/install/share/lua/5.1/luarocks/loader.lua:154: Invalid data in manifest file for module nn.THNN (invalid data for nn scm-1)
I have install nn. Repacing for_each with apply in /usr/local/share/lua/5.1/fbnn/Optim.lua didn't help either.
thanks.
