Gacutil doesn't demand elevation (it runs asInvoker) so I think that your
Visual Studio build isn't running elevated (I doubt you run it as
administrator), therefore gacutil won't run elevated and can fail to add
assemblies to the GAC.
It doesn't matter if you an administrator - default behavior on Vista is to
run as a limited user.

I learned that disabling UAC allows gacutil to succeed, but so does UAC
enabled and running VS as adminstrator. I appreciate the help for this Vista
newbie.
