Kudos to SymPy! I'm wondering why the python integration algorithms implemented there aren't in the short term adopted by SAGE. At least, they are already aware of their shortcomings (ie: cannot compute the integral of log(x)/x ).
I'm sure SAGE people could give big contribute to those, send patches upstream, and move forward if needed.
