open up src/Makefile, and comment out  the the line that looks like this:
$(MAKE) all MYCFLAGS=-DLUA_USE_MACOSX
and uncomment 2 lines below it that look like this:
#	$(MAKE) all MYCFLAGS="-DLUA_USE_MACOSX -DLUA_USE_READLINE"
MYLIBS="-lreadline"

It's pretty easy :)

For extra points, use this to build a universal binary:
$(MAKE) all MYCFLAGS="-DLUA_USE_MACOSX -DLUA_USE_READLINE -isysroot
/Developer/SDKs/MacOSX10.4u.sdk -arch i386 -arch ppc"
MYLIBS="-lreadline"
MYLDFLAGS="-Wl,-syslibroot,/Developer/SDKs/MacOSX10.4u.sdk -arch ppc
-arch i386"
