I don't think you uninstalled everything. I think the gcc version on your system is not compatible with Xcode 1.5. Humor me and tell me what you get when you enter this in the Terminal: gcc --version You should get this (this is from a Panther machine running 10.3.9): $ gcc --version gcc (GCC) 3.3 20030304 (Apple Computer, Inc. build 1666) Copyright (C) 2002 Free Software Foundation, Inc.

In any case I would do an Archive and Install from my installation DVD being sure to check the "Preserve user and network settings." Once your Unix underpinnings are restored, you should be able to successfully reinstall the Developer Tools that are compatible with your OS. Ken
