Distributions made on other machine types are not compatible:: |

False |
Distributions made on earlier versions of the OS are compatible, as |
long as they are from the same top-level version. The patchlevel version |
number does not matter:: |

True |

True |
>>> cp("macosx-10.5-ppc", reqd) |
False |
>>> cp("macosx-9.5-ppc", reqd) |
False |
Backwards compatibility for packages made via earlier versions of |
setuptools is provided as well:: |
>>> cp("darwin-8.2.0-Power_Macintosh", reqd) |
True |
>>> cp("darwin-7.2.0-Power_Macintosh", reqd) |
