You can do this in Java using PAL (http://www.pal-project.org).
PAL contains a class called TreeDistanceMatrix which does what you want:


To use this class you will have to program in Java.  If you don't want
to do that you could simply use the SHOWTREE program from the Vanilla


As PAL and Vanilla is written in Java it should run wherever you
want it to run.

Fast o(n^2) pseudo-code for this is in  D.Bryant and P. Wadell. 1998. MBE
