Warning: System.Web.dll built without parts that depend on: System.Web.Services.dll Mono.Web.dll

I am building mono (2.6.3) on开发者_高级运维 Ubuntu 9.10

I am getting the following error:

Warning: System.Web.dll built without parts that depend on: System.Web.Services.dll Mono.Web.dll

Does anyone know what is causing this, and how I may resolve this?

System.Web.dll contains a cyclic dependency on System.Web.Services.dll.

So what happens is Mono builds a version of System.Web that does not depend on S.W.S, then uses that to build S.W.S, and finally builds the final System.Web which replaces the first one.

This probably should not use the word warning. It is just the way things are, and it cannot be resolved.
