Trouble building a BizTalk orchestration with MSBuild

I've got a BizTalk 2010 project I am trying to build via Cruise Control .NET. The weird thing is that it's having trouble with the CompileODX target, within the XLangTask. I can compile via MSBuild.exe on the command line, and when my account runs Cruise Control. However, when Cruise Control is running as a designated service account, it fails. The service account has Full Control on a parent of the directory containing the references (I only have Read/Execute). The service account is a local Admin on the box running Cruise Control service and has been rebooted.

I added some logging within the target to output the parameters to the XLangTask task along with the errors.

It seems that the build process cannot locate your EnterpriseEventSchema, is the dll for this schema present in the GAC on the build server?
