After several days of attempting to install Sage on my MacBook (mid 2010) I'm about to give up.

First, I tried the binaries. Both the traditional version sage-6.8-x86_64-Darwin-OSX_10.10_x86_64.dmg and the app version sage-6.8-x86_64-Darwin-OSX_10.10_x86_64-app.dmg gave me an Unhandled SIGILL error when I attempted to run the simple expression 1.1+1.0 . The sage --testall failed with the same error in many tests.

I then attempted to build sage from the source code. The default Xcode clang compiler didn't work. Maybe because it doesn't have fortran and other prerequisites. I then downloaded and built the GNU gcc compiler. After several failed attempts to build sage with that I finally tried building sage with it's internal gcc compiler [export SAGE_INSTALL_GCC=yes] ... and that failed too. Both my built GNU gcc and sage's internal gcc compilers gave me the same error:

configure: Configuring included Boehm GC library:
/Users/<myid>/sage-6.8/local/var/tmp/sage/build/ecl-13.5.1.p0/src/src/configure: line 5963: /Users/<myid>/sage-6.8/local/var/tmp/sage/build/ecl-13.5.1.p0/src/src/gc-unstable/configure: No such file or directory
configure: error: Unable to configure Boehm-Weiser GC
Error - Failed to configure ECL ... exiting

Before I quit, can anyone offer any advice on what I should do?

Do you see a line like "checking whether we can use the existing Boehm-Weiser library ... yes" in sage/logs/pkgs/ecl-13.5.1.p0.log? Or does it say "no" at the end? Do you have fink or homebrew installed? Those should be disabled before building Sage, and their presence could be confusing the build process.

Quoting from README.txt:

OS X: Xcode. Make sure you have installed the most recent version of Xcode. With recent versions of OS X (OS X Lion or later), you can install Xcode for free from the App Store. For pre-Lion versions of OS X, you can download Xcode from

With OS X, you also need to install the "command line tools". When using OS X Mavericks, after installing Xcode, run this command from a terminal window:

  xcode-select --install

Have you followed these directions? If not, do these, try make distclean, and try building again.

Yes, I have the most current Xcode. xcode-select --install says command line tools are already installed and all my software is up to date.
