When we install the gnuplot on Mac OS X from the source code, we encounter this strange error message:
If you look at the /usr/lib/libreadline.dylib file, the symlink is pointing at a library file that we do not know. (Seems not familiar to me) Thus, we can solve this problem by installing libreadline from the source, and change the symlink properly. In my case:
Undefined symbols:This error is due to the readline library in Mac OS X.
