when I run itorch : I got this following, can you help me fix this
bash: /home/shravan/torch/install/bin/itorch: Permission denied

change permission to executable or use 'sudo'!

I suggest adding the following package to the install script to avoid the error below:
sudo apt-get install libssl-dev

You may have to install OPENSSL in your system and/or pass OPENSSL_DIR or OPENSSL_INCDIR to the luarocks command.
Example: luarocks install luacrypto OPENSSL_DIR=/usr/local
