> Hi, thanks for your help, but I did not understand pretty well where I should paste the folder MacOSX10.6.sdk. The path that you give me is the same path where I found the directory. Did I misunderstood your instructions? Could you give please a hand due to I need the program on my computer full working with some addons (r.stream.extract, r.stream.order, r.fuzzy, r.stream.basin and others that I wrote).<br>

Both can be downloaded free (the app was available only from the app store for a while) You really only need the CLI tools, but it doesn't have the SDKs.<br>
