if you get elfclass errors you don't have the right x86 packages installed
 fix:
  dpkg --add-architecture i386 (this is for debian, use equivalent on your OS)
  apt-get update (or yum)
  apt-get install libtbb2:i386 (or yum)

if you get missing library libtbb2.so you don't have libtbb2 package installed
 fix:
  apt-get install libtbb2 (or yum, if on x86)
  apt-get install libtbb2:i386 (or yum, if on x86_x64)
