It would be best to open a ticket. > Hints on further relevant information ? IMHO, the way Sage calls Mathematica is not optimal. I recall opening a ticket before, when Sage would not work with my version of Mathematica. It turns out that the optional interfaces like Mathematica were not tested regularly - I don't know if that has changed. If you look at this post a month or so by me: https://groups.google.com/forum/?fromgroups=#!searchin/sage-devel/mathematica$20kirkby/sage-devel/tF5QApfHUHE/3FRgjYrg1QsJ you will see I had intended emailing something to the FSF and Wolfram Research to try to get a better way of interfacing to Mathematica. What responses were received from Sage developers, were negative, so I never bothered emailing Wolfram Research or the FSF. Technically the best way to produce an interface will be using the MathLink protocol in Mathematica. The issue is the license condictions of this. It can be used free for commerical use, but not for commerical use. This conflicts with the GPL, though I'm not convinced that could not be circulated if the interface was an optional component, that did not by default link to the Mathematica libraries. There is an open-source (GPL) program called 'jmath' http://robotics.caltech.edu/~radford/jmath/ which links to Mathematica in a way that is technially better. Exactly what the legal situation of that is, I don't know, and if you read the authors comments, he had conflicting answers from different sources. That was why I intended emailing the FSF and Wolfram Research. But as I say, all comments were negative.
