Jam Packs missing from Garage Band

Hi,

I have recently iLIfe'11 installed with all available updates (from the retailer DVD), GarageBand v.6.0.5. Whenever I launch it Console displays these messages:

04.03.15 1:19:13,218 [0x0-0x44044].com.apple.garageband: No receipt for 'com.apple.pkg.GarageBand_Jam_Pack' found at '/'.

Indeed, when I went to /private/var/db/receipts I found no signs of any .BOM files that would attribute to anything having "JamPacks" in its title. Both ~/Application Support/Garage Band and /Audio/Apple Loops folders have it neither. So I wonder: does this version of Garage Band have to have JamPack, the more so, JamPack 1 which, as I learned from Wikipedia, was discontinued as far back as in 2006(!)? If it does NOT then why does it report of not founding these receipts? To test whether this type of console messages occurs in other iLife'11 apps I launched the rest of them and it doesn't. So what is the story with this JamPack and can its absence affect GB functionality in future?

Kindest regards,

I.S.
