Comment (by pawrsccouk@…):

 I am getting the same issue with lua 5.2.3 as of 7th July 2014.

 Looking at the build, it appears that readline is invoked when building
 the object files for the lua library (liblua.dylib) but is not invoked
 when building the lua executable.
 In the makefile at
 {{{/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_lang_lua/lua/work/lua-5.2.3/src
 }}}
 The line building the final executable is
 {{{
 $(LUA_T): $(LUA_O) $(LUA_A)
         $(CC) -o $@ -L. $(MYLDFLAGS) $(MYCFLAGS) $(LIBS) -llua lua.c
 }}}
 If I change this to
 {{{
 $(LUA_T): $(LUA_O) $(LUA_A)
         $(CC) -o $@ -L. $(SYSCFLAGS) $(MYLDFLAGS) $(MYCFLAGS) $(LIBS)
 -llua lua.c
 }}}
 and recompile, then it uses the readline library as expected.  This is at
 line 69 of the Makefile.
 It appears that SYSCFLAGS is not passed to the compiler. This is the
 variable that includes the header definitions for the macosx platform,
 which causes readline to be selected in luaconf.h.
