SymPy 0.7.1 is the latest released version. We just haven't released
in a while.
I just checked, and this integral has not ever worked in master. It
didn't work in integration3 either. These things can depend on things
like assumptions or even architecture, though.

Actually, this has nothing to do with the algorithm I implemented.
The Risch algorithm is accessible in my branch through the
risch_integrate() function, and it only works with a limited class of
functions that does not include this one.
By the way, this integral works in master:
In [70]: integra
Wow! You really made some progress and I can't believe it hasn't been
merged into the main code. I had given up on sympy for a lot of my
work because the integration starts to break on really simple
integrals, for instance from the latest 0.7.1.rc1:
In [1]: c=symbols('c')
In [2]: integrate(1/sq
How can you do anything useful with it if you don't have a detailed
idea about how the Risch algorithm works? What you should do next is
find out something (on your own or use the issues page) that is
broken, fix it and send a patch. The community will then review the
patch and provide you feedback
