I'm not sure that there's any problem with the readline-5.1 install.  You
can verify that by running

ls -l /usr/local/lib/libread*
ls -l /usr/local/lib/libhist*

The problem is probably that, for some unfathomable reason, Apple wrote
a virtually non-functional readline "replacement" module for libedit and
shipped it in /usr/lib.  Unless you specify /usr/local/lib when linking
ruby, and relink it now that you've got a genuine version of readline
installed, it will use /usr/lib/libreadline.dylib and fail to run.

I have run into that problem already.  Bash contains special config code
to ignore /usr/lib/libreadline.dylib when built on OS X.
