cutorch require problem

[shimen]

I had made a full torch install after using clean-old.sh to clean all the old versions.
I have a problem with cutorch scm-1.
I had installed it with: luarocks install cutorch
When I run the command: luajit -lcutorch
I get:
ilyas@s29.black.bionic8.com ~$ luajit -lcutorch
luajit: /usr/local/share/lua/5.1/cutorch/init.lua:2: cannot load '/usr/local/lib/lua/5.1/libcutorch.so'
stack traceback:
[C]: in function 'require'
/usr/local/share/lua/5.1/cutorch/init.lua:2: in main chunk
[C]: at 0x0044cfb0
[C]: at 0x004054a0

When I install cutorch with this command: luarocks install cutorch 1.0-0
I get:
ilyas@s29.black.bionic8.com ~$ luajit -lcutorch

Same for cunn just the cunn 1.0-0 works with cutorch 1.0-0, the cunn scm-1 does not work.
cudnn also not working

Dose the last version works only with cuda 8.0 or it still supports cuda 7.5?
