xmkmf's Makefile.am does not copy the result of the monolithic imake result. This patch fixes includes for finding the xorg-cf-files install.
Created attachment 3528 [details] [review] Makefile.am.patch To be applied in modular's xmkmf directory.
Sorry, that should read "does not copy the monolithic imake result."
Committed a functionally identical change, with a little less quoting and without renaming XCONFDIR.
