I got this out of the blue today on our CI server.

No code was changed ! Nobody touched the server, and I started getting these errors.

Did you find a solution?

Well, I found a workaround, detailed here: http://stackoverflow.com/a/10980391/11236

The root cause for this is still unclear - it seems our dependencies changed on this machine overnight, for no apparent reason.
