	How 'bout if you remove "module" directory (and perhaps also the dir
containing libpangox) from the SUBDIRS line (but keep it in DIST_SUBDIRS or
whatever that variable's called).  Then add something like the following:

# Build pango compiled-in modules
modules-builtin:
	$(MAKE) -C modules modules-builtin

# Build pango dynmaic modules
modules-dynamic:
	$(MAKE) -C modules modules-dynamic

dnl Okay, this goes somewhere else if you're using Automake, but I think you
dnl get the idea...
all: modules-builtin libpangox modules-dynamic

	Admittedly, I haven't looked into the tree recently, so I don't know
how well this will actually work.  However, I /think/ it will solve your
problem.
