What causes this? It's using the 10.4 SDK... I'm trying to make the program compatible at least back to 10.4. Sometimes this works, sometimes it doesn't... What causes this problem that must have changed? (I also get something about build.hmap being/not being a directory — that's fixed by cleaning the build.)
You've installed some code (I wish I knew what it was, it seems pretty popular) that puts a PPC-only version of several graphics libraries in /usr/local/lib, superseding the system's Universal versions. When you link your Intel code against this PPC-only library, it gets the above error.
The solution is to remove those librariesfrom /usr/local/lib, or remove the symlink from MacOSX10.4u.sdk/usr/local.
