Hello Guangjian,

I do not have a copy of OS X 10.5.8 to test with (what I have is 10.7.5,
which mlpack appears to compile fine with).  Based on my best guess, I
have written and attached a patch that may work for you.

If it does not, perhaps you can try upgrading to a different system?  We
can go back and forth with patches until we get it to work, too, but
that could potentially take some time to get right (unless the patch I
have attached works and is the only necessary one).

Thanks,

Ryan
