See:

Also note that, as shown in the instructions, you should be building as 
"user" (denoted by the $ .... i.e. "$ make" ), then install as "root" 
(which, in the instructions, is achieved through "sudo make install" 
...... if the instructions called for being the root user all along, 
then the cli prompt would be denoted by a #, and there would, of course, 
be no need for the use of a "sudo" .... sudo allows one to invoke the 
superuser's privileges in respect to performing some command i.e. "sudo 
command".

In any regard, building as root user will generally work, BUT you are 
exposing yourself to the risk/potential of introducing system changes 
that could very easily vary from being entirely benign to entirely 
destabilizing ... [dirty harry mode] being that this is root, the most 
powerful user in the Linux world, and will blow your installation clean 
off, you gotta ask yourself a question --- do I feel lucky? .... Well do 
you punk?[/dirty harry mode]
