The best approach I know of as yet is the maximum likelihood method
of Joseph Felsenstein  Dept of Genetics, Uni of Washington, Seattle
eg "Inferring Evolutionary Trees from DNA Structures"
   Statistical Analysis of DNA Sequence Data
   (ed) B. S. Weir,   Marcel Dekker inc  1983  p133-150
This has excellent statistical validity.
It may not be practical if your tree is very big.

JF distributes a package containing several tree building methods
for free.  This includes a parsimony method and a M.L. method.
