Installing ROOT on CentOS 5

I am trying to install ROOT onto a CentOS 5 machine from the source and whenever I get to this point in the installation from source instructions:

cd root ./configure

entering the command ./configure returns the following:

I’m a bit puzzled as to why this is happening. Are there any file paths that I need to change around in the makefiles so that ./configure functions properly, or is there nothing that can be done?

if you try in the same directory

what it returns?

Have you downloaded the correct compressed package? Make sure you choose the souce, not the binary. The name of compressed package should look like root_.source.tar.gz
There is no configure file in the binary package.
