Hi,
MEGA does this. It's a PC program, costs $25 (when I last looked) and
it's also a nifty tree-building package. It's written by Kumar, Tamura
and Nei.
Kumar S, Tamura K, Nei M. 1994
MEGA: Molecular Evolutionary Genetics Analysis software for
microcomputers.
Comput Appl Biosci 10(2), 189-191 (1994)
