The issue is that ReportViewer is not part of the .NET Framework. However, when Visual Studio 2005 is released, ReportViewer will be freely redistributable. You will be able to run a setup program to install ReportViewer on the target machine.
The workaround for now is to manually copy the following assemblies to the target machine (either to the bin directory or to the GAC):
Microsoft.ReportViewer.Common.dll
Microsoft.ReportViewer.ProcessingObjectModel.dll
Microsoft.ReportViewer.WebForms.dll
Or Setup up the ReportViewer.exe Form Microsoft Website.
