Handling Dependencies

The easiest way to get all dependencies installed and kept up to date with minimal effort is to use fink. To get all the dependencies install glob2 from fink. Fink will take care of getting all the dependencies installed for you. At this point you can leave glob2 installed or not, doesn't really matter

on to glob2 itself and Mercurial
