Ruby 1.8.5 and Readline on Mac OS X 10.4.8 (Intel)

The readline "problem" on OS X has nothing to do with ruby
1.8.4/1.8.5/whatever. The issue is that there is a partial "readline"
library in /usr/lib (libedit or something...) and that is what your
build is linking to by default (as /usr/lib comes before /usr/local/lib
in the link path). Rrebuilding using the
--with-readline-dir=/usr/local configuration option should fix it
(assuming you have installed the true readline in /usr/local).

i have always used james duncan davidson’s Sandboxing Rails With MacPorts
without issue:
<http://blog.duncandavidson.com/2006/04/sandboxing_rail.html>

he also provides some color on install source vs. macports.
