For interlandmark distances from the original raw coordinates (no need to superimpose and rescale), one can use the EDMA function of PAST. Julien also has a script in his book to compute ILDs pairwise and the old Morpheus et al. had a command to get specific ILDs (this was also an option in PAST 2 and probably later versions).
