Ah. Choudhury et S. Power, A NEW APPROXIMATE GLS ESTIMATOR FOR THE LINEAR-REGRESSION MODEL WITH ARMA(P,Q) DISTURBANCES, Economics letters, 48(2), 1995, pp. 119-127
This paper introduces a new approximate GLS estimator for the linear r
egression model with ARMA (p, q) disturbances, which involves a simple

y basic econometrics package.
