Jim, I don't know why Fink didn't put readline where Fink is looking for it
but you should already have readline installed in:
/System/Library/PrivateFrameworks/readline.framework/readline

So the question is "Why isn't require finding the readline that's already
installed in OSX?" Or maybe a better version is "How come Chris's version of
irb finds readline down in /System/Library/... while Jim's does not." None
of the Frameworks actually show up in my $: path.

Well I don't have a definitive answer but I suspect that it's because I
built ruby with --enable-shared as Fujimoto Hisakuni suggested. I went down
the path with someone else on this list who didn't have ncurses and that
turned out to be the difference.

Please see if using -enable-shared works for you. If it doesn't, post again
and we'll work through it.

From memory though, --enable-shared forces the static linker, ld, to build a
version of ruby that gives the dynamic linker, dyld, a chance to satisfy
externals at runtime.
