The readline egg does not install on OS X 10.6 (Snow Leopard) due to a
mismatch between the readline library that ships with the base OS X
system (under /usr) and what the egg's expecting. I suspect, but have
not verified, that OS X is shipping a much older version of readline.
Fortunately, the readline in MacPorts works with the readline egg; it's
just a matter of getting chicken-install to compile and link against
/opt/local. To do that, I hacked readline.setup. Here's what I did:
First, fetch a local copy of the egg:
% chicken-install -r readline
THen apply this patch to readline/readline.setup:
% diff readline/readline.setup readline-hack/

...and then install from the readline subdirectory:
% cd readline
% chicken-install
Though it builds and installs cleanly, saved history doesn't seem to be
working; I haven't bothered to figure out why. For reference, the
relevant portion of my .csirc looks like this:
(require-extension readline)
(current-input-port (make-gnu-readline-port))
(gnu-history-install-file-manager
(string-append (or (getenv "HOME") ".") "/.csi.history"))
I've attempted to attach transcripts of before and after to this post,
along with the above patch. If they don't come out, I'll add them as
follow-on replies. I recently switched back to gnus and haven't had an
opportunity before now to try out this new-fangled MIME support...
