Where are you running into problems? Is it in the conversion to power series, or is it in the integration of the series? (That changes the question entirely) –  anorton Apr 8 '13 at 1:48

$$\log{(1-t)} = -\sum_{n=1}^{\infty} \frac{t^n}{n}$$

$$\int dt \frac{\log{(1-t)}}{t} = -\sum_{n=1}^{\infty} \frac{t^n}{n^2}$$
