Once again, with enthusiasm, you'll need to explain your complete build process for
anyone to be able to help you.
   * What's your build host
   * What version of Poky/Yocto are you using
   * What is your target MACHINE
   * What, if anything, have you added to local.conf

Without this kind of information, answers would be only guesses...
