Longitude Latitude distance calculation

I am doing an application in Xcode with Applescript and shell scripts ...
... do anyone know how I can get a distance between two points (long1, lat1, long2, lat2)
based on this formula (with apple or shell script?):

Distance between points:
The great circle distance d between two points with coordinates {lat1,lon1} and {lat2,lon2} is given by:

d=acos(sin(lat1)*sin(lat2)+cos(lat1)*cos(lat2)*cos(lon1-lon2))

A mathematically equivalent formula, which is less subject to rounding error for short distances is:

d=2*asin(sqrt((sin((lat1-lat2)/2))^2 +
cos(lat1)*cos(lat2)*(sin((lon1-lon2)/2))^2))

Thanks!
