You should look at the Align::DNAStatistics module if you just want
pairwise DNA distance. I put in several different distance methods.
Or you can use the distance methods implemented in PHYLIP or EMBOSS
programs -- I thought you wanted the somewhat more sophisticated ML
approaches that are implemented in PAML?
