Installation problems under Mac OS X El Capitan v10.11.6

[Roger‏]

Hello, I am having problems installing Sage under Mac OS X El Capitan v10.11.6.  I successfully downloaded the file sage-7.2-OSX_10.11.4-x86_64.app.dmg (the most recent version).  After mounting the volume and copying the application to the application folder and launching, the Sage menus appear, and a terminal window appears, but with the error messages as shown below.  Any help would be greatly appreciated!  Thanks, Roger

Terminal window contents:

well, 7.3 has been just released. Hopefully the binary builds will be available shortly, and for the right version, i.e. for  OSX 10.11.6.

Thanks for the info re the new 7.3 release.  How long does it typically take after a new release for binaries to become available?  Before a formal release, are beta binaries available for testing, and if so where, or how can one volunteer with the developers as a beta tester?  I know that's a lot of questions, but thanks in advance for any guidance on these points.

Also, in case there are any suggestions out there for alternate open source solutions, for the current project, I am primarily involved in solving systems of multivariate first order polynomials, where each term is a product of any number of the system variables and a coefficient, but where all variables are of first order, i.e. exponent of one.  There can be on the order of one hundred variables and equations.  I'm interested in both numerical and symbolic solutions.  Thanks again.

We do not build binary distributions of betas or release candidates.
(Well, the buildbots do test builds all the time, but these are neither
"bdists" nor do they get published, just the reports.)

But you can obtain the sources of all beta/rc/final releases and build
yourself from source:

http://www.sagemath.org/download-latest.html

(The sources for 7.3 *final* will appear on [1] soon.)

On MacOS X, you'd need Xcode and/or the Command Line Tools [2], in
general the latest version available for your OS version.

(The binaries we publish can be produced from such a build, with some
restrictions on build options, but that's a further step.)


See [3] for instructions on how to build from source.

As a complement to Leif's answer, if you are interested in hearing

about beta releases and trying to build them on your platform,

you can subscribe to the sage-release mailing list:
