[Mono-list] Xbuild fails

[Matt Calder]

Hi,

I am working with a Solution primarily with Monodevelop. However, we deploy
this solution to the cloud and there we build using xbuild. Recently, that
build started failing with this trace:

calder at pharos:~/Work/Lightkeeper/lightstation$ xbuild LightStation.sln
XBuild Engine Version 2.11.0.0
Mono, Version 2.11.0.0

Anyone have an  idea of what is wrong?
