Configure looks at ARCHFLAGS from the ENV, and it adds it to all compilation just like CFLAGS. But python distutils will only see it if set in the ENV, before configure. If set inline with configure command (ie configure .... ARCHFLAGS=), it doesn't get added to python compilation. Adding it inline with the make command sets it in the environment so that only python compilation sees it, which may best so that it doesn't hide other unknown flag errors in general compilation that may need to be fixed (ie find alternatives). ----- William Kyngesburye <kyngchaos*at*kyngchaos*dot*com> http://www.kyngchaos.com/ "We are at war with them.
