If you have the phredPhrap package already, you might find cross_match 
sufficient. Convert your phd files to a fasta and qual files using 
phd2fasta. When you do the comparsion with cross_match, a large table of 
the quality values of the mis-matches is generated. Not sure if it is 
what you are looking for. I generally am looking for ways to filter out 
this output. Help is at www.phrap.org.
