WO Deployment installation

I have just installed Panther Server on a PowerMac G4 from a very recently 
purchased disk. I forgot that WebObjects Deployment is pre-installed and 
went ahead and installed WO5.2 Deployment from my installation disk.

I then expected Sofware Update to pick up WO5.2.2 update (I don't want to 
go to WO5.2.3 yet). But software update doesn't come up with it and I can't 
see a download for 5.2.2 update at the Apple site.

Can anyone advise on how to get my WO installation to WO5.2.2 or how to 
check which version it is on. I can see /Library/Receipts/WODeployment.pkg 
but can't decipher the contents.

Thanks
John
