Hi, I'm trying to compile boost 1.33 on MacOS X, and I get a number of failures. I have: $ uname -a Darwin akos-maroys-mac-mini.local 8.2.0 Darwin Kernel Version 8.2.0: Fri Jun 24 17:46:54 PDT 2005; root:xnu-792.2.4.obj~3/RELEASE_PPC Power Macintosh powerpc $ gcc --version powerpc-apple-darwin8-gcc-4.0.0 (GCC) 4.0.0 (Apple Computer, Inc. build 5026) Copyright (C) 2005 Free Software Foundation, Inc.
