"The dependency... could not be found", but it's RIGHT THERE.

I have a .NET solution that displays the following in the Task List: "The dependency 'Microsoft.Vbe.Interop' could not be found".  The dependency is apparently inherent in one of my references: Microsoft.Office.Interop.Excel.  This fits with the msdn reference ( http://msdn2.microsoft.com/en-us/library/15s06t57.aspx ) which claims that the Microsoft.Vbe.Interop.dll is added automatically when using one of the Office primary interops.  Unfortunately, I got my Microsoft.Office.Interop.Excel.dll from the project directory, and there's nary a Microsoft.Vbe.Interop.dll to be found there or on my drive.

The same msdn page I reference above mentions a Microsoft.Vbe.Interop.dll in the 'Available Assemblies' associated with the Microsoft Visual Basic for Applications Extensibility 5.3 component.  I added a reference to that COM object, which creates a reference labeled Interop.VBIDE and one labeled VBIDE.  The 'Name' property for VBIDE is Microsoft.Vbe.Interop, and the path is C:\WINNT\assembly\GAC\Microsoft.Vbe.Interop\11.0.0.0__71e9bce111e9429c\Microsoft.Vbe.Interop.dll.

This seems like it ought to work, but it doesn't.  If I add or remove the VBIDE reference(s), nothing changes.  I still see "The dependency 'Microsoft.Vbe.Interop' could not be found", and I still can't successfully build.  

Any suggestions would be appreciated.
