Seems that the buildoptions set the CPU to G3, wich of course does
not exist on an Intel arcitecture.
You need to open all the xcodeproj-files and look at the "Target"-Get
Info dialog. In the build Tab you'll find "Other C Flags" from wich
you have to remove "-mcpu=G3"
Be sure to do that for the KisMac.xcodeproject as well as for all the
projects in the /Subprojects directory.
