Leave standard paths at the end, as the system might be completely |

32bit but running on 64bit-capable CPU. |

CAVEAT: This is bit dangerous, as on 64bit OS, if ia32 libs are |

63 |
not installed byt 64bit sqlite libs are, then 64bit libs are found |
|
64 |
and when a function is called, segfault will occur!! |
