 	* backends/Makefile.am: Add SOCKET_LIBS to xerox_mfp
 	for platforms such as solaris since it uses sanei_tcp.k
+	* doc/sane.tex: removed reference to changelog package
+	since its not used and not installed by Macports (#312596)
+	* doc/Makefile.am: put quotes around TEXINPUTS in case
+	paths have spaces in name.  This is so latex can find
+	html.sty package that is referenced by sane.tex.
