Apple's compilers are buggy. Also, before I could install the OS X command line tools, I had to first install XCode. People keep suggesting on this thread that the command line tools are currently an *alternative* to XCode, but for me at least that did not seem to be the case. -- William > --Jason > > > > On Thu, May 24, 2012 at 10:32 AM, Jason Grout > <jason-s...@creativetrax.com> wrote: >> On 5/24/12 9:45 AM, Jason Ekstrand wrote: >>> >>> Here is the problem: Sage 5 ships with GCC bundled in so that mac >>> users can install sage and build sage packages without having to have >>> the mac build toolchain (It makes sage much easier to install for the >>> end user).
