Mac OS X Prebinding?

What is prebinding dynamic libraries?

Prebinding your dynamic libraries makes them depend on the system's current library versions and locations. This makes the executable faster when it is starting, but library versions and locations are liable to change between OS versions. When library versions and locations change, the prebinding information is no longer valid and is ignored. From that point on, the prebinding information is just taking up space. You can, however, update your prebinding information with the "redo_prebinding" command.
