	Yes I'm building in the source tree.  That's what I meant when
I said "builddir == srcdir". :-)   What exactly wasn't found during
your build?  Were you using a relative or hard path to your srcdir?

	The following solves the problem I saw.  Since your build
didn't find something it was looking for in the object directory, this
might not solve your issue.  But let me know either way.
