Unity Asset Server Installation problem on CentOS

Hello,

I am using the method below from this page: http://unity3d.com/asset-server/

"Installing from source We recommend that you try installing the rpm first. Should that fail, you can try compiling it yourself from the source tarball. Before attempting the installation please make sure you have the following installed on the server machine:

make gcc bison perl On the server machine, run the following commands as root:

wget http://download.unity3d.com/asset_server/unity_asset_server-2.0.1.tgz tar xvzf unity_asset_server-2.0.1.tgz cd unity_asset_server-2.0.1 ./install.sh"

I have full root access on CentOS. and I type in ./install.sh, and I get this below. What do I have to do next?

Thank you for any help.
