Some of our clients give us the following warning when referencing Cake.WebDeploy.

Could not load C:\WINDOWS\Microsoft.Net\assembly\GAC_MSIL\Microsoft.Web.Delegation\v4.0_7.1.0.0__31bf3856ad364e35\Microsoft.Web.Delegation.dll (missing Microsoft.Web.Administration, Version=7.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35)

With the old version 0.3.4 we had no issues. Any idea, what could be wrong?
