I got 56 failures on Solaris. A log can be found at http://sagetrac.org/sage_trac/attachment/ticket/6709/test.log But I do not think Sage has ever passed all tests on SPARC, so I suspect some of these might be Solaris specific. Clearly some are not though. This 'failure' is actually an improvement. sage: integral( exp(-x^2)*ln(x), x, 0, oo) Expected: integrate(e^(-x^2)*log(x), x, 0, +Infinity) Got: -1/4*(euler_gamma + 2*log(2))*sqrt(pi) Currently the Maxiama update http://sagetrac.org/sage_trac/ticket/6699 is marked as '[with spkg; needs work]' but there is nothing I can do to it. The package itself installs ok, and executes roughly how one would expect. My own view would be to stick this in an alpha.0 release, complete with the failures, then sort out the issues before making a new 'supported' release. It needs a bit more work than most packages and it is work for the most part I'm unable to do. (I'm not a mathematician).
