Something very similar happened to me some time ago with a another
project.  In that case, the first make was expecting temporary files,
It made them, but didn't wait for the IO to finish so that when the
file was opened, it really was there.  On the second make pass, the
file wasn't made because it was present.  Making the second attempt
succeed.

I can't say if this is your issue or not, but its worth looking at.

Hope this helps.
