Installation of 2.9.12 - readline problem?

[Vic Norton]

I am currently running Octave 2.9.9 from High Perfomance Computing  
<http://hpc.sourceforge.net/> on Mac OSX 10.4.10. It works perfectly.

I thought of trying to install Octave 2.9.12 (but not "Octave.app").  
The end of my "./configure" output reads
   checking for rl_set_keyboard_input_timeout in -lreadline... no
   configure: WARNING: I need GNU Readline 4.2 or later
   configure: error: this is fatal unless you specify --disable- 
readline

I can't figure out what the problem is. I have GNU Readline 5.0  
installed:
   /usr/include/readline
   /usr/include/readline/history.h
   /usr/include/readline/readline.h
   /usr/lib/libreadline.dylib
   /usr/local/include/readline
   /usr/local/include/readline/chardefs.h
   /usr/local/include/readline/history.h
   /usr/local/include/readline/keymaps.h
   /usr/local/include/readline/readline.h
   /usr/local/include/readline/rlconf.h
   /usr/local/include/readline/rlstdc.h
   /usr/local/include/readline/rltypedefs.h
   /usr/local/include/readline/tilde.h
   /usr/local/info/readline.info
   /usr/local/lib/libreadline.5.0.dylib
   /usr/local/lib/libreadline.5.0.dylib.old
   /usr/local/lib/libreadline.5.dylib
   /usr/local/lib/libreadline.a
   /usr/local/lib/libreadline.dylib
   /usr/local/lib/libreadline.old
   /usr/local/man/man3/readline.3
What am I missing?
