Apple Lion Recovery Update para Mac

Got the error "Lion Recovery Update can't be installed on this disk. An error occurred while evaluating JavaScrip for the package" Installer Log says Oct 13 10:07:00 Installer[6749]: recoverySystemVersion: could not get recovery version information for mount point /: Unable to find boot helper partition. (-69737) Sounds like it never got setup in the first place -- now to find out how to set it up? I thought I read this is only supported on newer Macs, so what about Mid-2009 MacBook Pro?

For folks with both a Lion Recovery Partition and a TechToolPro eDrive partition already installed, Lion Recovery Update (running under 10.7.2) may report that it is unable to create a Recovery Partition and offer you the 'option' of Cancelling the installation. My workaround was to mount the existing Lion Recovery Partition, using Disk Utility, and then run Lion Recovery Update. Seems to have worked like a charm.

This update is stupidly large. I suspect it's just an image that your current recovery partition is replaced with... It was the same size from Software Update, so it's not just that the standalone is larger. How about a proper delta update that's not over 400MB, Apple? Surely you didn't re-engineer the entire recovery setup from scratch. I don't mind downloading 400MB for an update to a fairly minor component of my system, but I know there are a LOT of people who do.
