  We present the calculation of the nf-contributions to the two-loop amplitude
for e+ e- --> q qbar g and give results for the full one-loop amplitude to
order eps^2 in the dimensional regularization parameter. Our results agree with
those recently obtained by Garland et al.. The calculation makes extensive use
of an efficient method based on nested sums to calculate two-loop integrals
with arbitrary powers of the propagators. The use of nested sums leads in a
natural way to multiple polylogarithms with simple arguments, which allow a
straightforward analytic continuation.
