Failing to build Lua 5.3.5 on Macbook

[Daryl Lee <daryl@...>]

Greetings!

I have both an iMac and a Macbook pro laptop, both running Mojave (OS X 
10.14.1), both with XCode 10.1, both with command line tools (gcc 
--version reports Apple LLVM version 10.0.0 (clang-1000.11.45.5)).  Lua 
5.3.5 builds and runs nicely on the iMac, but fails on the Macbook, with 
several linker errors, beginning with:

gcc -std=gnu99 -O2 -Wall -Wextra -DLUA_COMPAT_5_2 -DLUA_USE_MACOSX    -c 
-o lua.o lua.c
gcc -std=gnu99 -o lua   lua.o liblua.a -lm -lreadline
Undefined symbols for architecture x86_64:
  "_tgetent", referenced from:
      __rl_init_terminal_io in libreadline.a(terminal.o)
  "_tgetflag", referenced from:
      __rl_init_terminal_io in libreadline.a(terminal.o)
  "_tgetnum", referenced from:
      __rl_get_screen_size in libreadline.a(terminal.o)
...

Any suggestions would be appreciated.
