Macro behavior depends on method of code loading?

I have two identical versions of a macro that prints all exported names of a given module. One version is imported from a package; the other is defined globally. The former fails while the latter succeeds. What am I doing wrong?

The package:

module JuliaUtils

macro modulenames_from_package(module_) 
    return quote 
        names($module_)
    end 
end 

end 

The REPL:

using JuliaUtils:  @modulenames_from_package
using Example 

macro modulenames_global(module_) 
    return quote 
        names($module_)
    end 
end 

julia> @modulenames_global Example  # works 
3-element Array{Symbol,1}:
 :Example
 :domath
 :hello

julia> @modulenames_from_package Example # FAILS -- why???
ERROR: UndefVarError: Example not defined
