Trying to upgrade to gw2012sp1. I cannot get started due to my schema
not upgrading. I keep getting the message:

Add attribute homePhone to class GroupWise External Entity.

I've tried this several times in C1, plus have tried to manually add
this via iManager, all to no avail. I don't have the gwschema.sch to
run the ndssch command.

I don't want to continue until I get this resolved, help!
