Rather than using the name of the keg for the key use the full path. This provides several advantages: - there's no need to invalidate the cache on a `brew upgrade` or `brew switch` - it's easier to figure out what cache entries can be removed and this can be done whenever a keg is removed by `brew uninstall` or `brew cleanup`. Also, ensure that an `install` (or `reinstall`, `upgrade`) always results in the cache being rebuilt for that keg (in case different options were used).
