Undefined symbols means a library is missing.  readline.h gives 
reference to the _rl_forced_update_display function but -lreadline does 
not have it.  There are several reasons why this may happen, of which a 
few are easy to fix.

Question: what version of readline do you have?

The easiest fix is to use --without-readline on your configure line.
