Some hints & guesses:

".dylib" means it is a Mac OS/X Dynamic Library & thus a OS/X specific
problem. It seems r.mapcalc was compiled with readline 4.2.0 headers
while the main system libary for readline on your computer is only 4.0.0.

You might have two versions on you computer, but I'd guess you are
trying to use binaries compiled on someone elses (more up to date) OS/X
system.

Binary install:
Try updating the system's realine libraries (fink?) to 4.2.0.

Source install:
Try compiling without the --with-readline ./configure option, it isn't critical, I think.
