zip task Problem loading SharpZipLib

I downloaded the latest version of NAnt and NAntContrib, and tried to use a simple zip task in my NAnt script.

The version of SharpZipLib.dll that comes with NAnt, in <path>\NAnt\bin\lib, is 0.84.0.0. 

I tried downloading the latest version of SharpZipLib, renaming ICSharpCode.SharpZipLib.dll to ICSharpCode.SharpZipLib.dll.bak, and putting the new version in its place, and the new file is version 0.85.4.369.

Looking at the error reported below (with Fusion logging turned on for extra verbosity), apparently NAnt.exe depends upon version 0.85.1.271 of SharpZipLib and won’t load either of the above versions.

Anybody know how to resolve this issue?

Thanks,

Mark
