On the plus side, on the laptop where I had problems before, Sage built and passed all doctests using the default compiler: $ gcc --version i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.9.00) Copyright (C) 2007 Free Software Foundation, Inc.

I'm going to build with SAGE_CHECK=yes to see what packages fail self-tests, but Apple seems to have fixed some of their compiler bugs in this latest release. -- John -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
