I looked at a bioperl method, but can't seem to find something that will
accomplish this.

Yes, I agree.  I suppose the best way would be to specify the two
sequences and the blast output.  The application could then construct an
alignment based on a particular HSP (probably the first one, or whatever
the user specifies).
