    CMake Warning at CMakeLists.txt:81 (message):
      This is a 64-bit system, but Armadillo was compiled without 64-bit index
      support.  Consider recompiling Armadillo with ARMA_64BIT_WORD to enable
      64-bit indices (large matrix support).  MLPACK will still work without
      ARMA_64BIT_WORD defined, but will not scale to matrices with more than 4
      billion elements.

Then I tried the repo part downloaded from build [   Also the cmake-2.8.6 it didn't work either.
It seems to be that the path of "libboost_program_options-mt.so.5" is dublicated with "lib64",
I searched by google, a link [http://stackoverflow.com/questions/9948375/cmake-find-package-succeeds-but-returns-wrong-path](http://big.cc.gt.atl.ga.us/job/mlpack%20-%20svn%20checkin%20test/ws/repo/]

It's the first time that I create a ticket here. And I don't know how to set the tags like "priority", "component" etc. Sorry for that.
