The funny thing, though, is that when readline installs in /usr/local/lib/, it 
seems it ends up at the end of the library search path; 'man ld' says:
  Search paths
   ld maintains a list of directories to search for a library or framework to 
use. The default library search path is /usr/lib then /usr/local/lib. The -L 
option will add a new library search path.

I am not sure how to interpret this: I think that -L actually adds the new 
directories at end of the search path, whereas -I adds them at the beginning. 
That seems anyway to be the case with /usr/local/lib/ searched after /usr/lib/.

I have though checked that on my system, guile-2.0.0 links dynamically to
  /usr/local/lib/libreadline.6.1.dylib
and not to libreadline.6.dylib or libreadline.6.dylib.
