I think the right fix for this is to special case --help to bypass more checks and to happen earlier. For instance if you don't happen to have a 'python' on your PATH then we do this: netbsdvm# ./configure --help ERROR: Python not found. Use --python=/path/to/python I'll have a go at writing a patch. thanks -- PMM
