  Compile with scons:
   
       sudo scons prefix=/usr install
  
  You can also optimize for a particular CPU if you are using GCC 4.2 and above:
  
       sudo scons preix=/usr install **optimize=#**
  
  "#" depends on your CPU. You can optimize with the following:
  
  1:  single-core (P-III and below)
  2:  P4
  3:  Intel Core
  4:  Core 2
  5:  Athlon-4/XP/MP
