you need to extract the file, then you enter the folder that is extracted through terminal. Then you should see avaulability of folder src and file configure. if that is not the case I cant help you. but if those files are present then on the terminal you've opened type "./configure", after some lines coming and going, you should again type "make", and then at last "make install" then the program gets installed. if this not work as planned or some message shows to get dependencies you should get them first.
