Everything
seems quite functional, except that readline produces the following:

configure:21277: checking for rl_callback_read_char in -lreadline
configure:21307: cc -xarch=v9 -o conftest -xO5 -xlibmil -dalign
-I/usr/local/include -L/us
r/local/lib conftest.c -lreadline  -ldl -ltermcap -lm  >&5

ld: fatal: Symbol referencing errors. No output written to conftest
configure:21313: $? = 1
configure: failed program was:

in config.log...  do I interpret this correctly as a gentle suggestion
that readline should be remade as a 64bit library?  Can this be done?

Yes, yes.  You need to build it with cc -xarch=v9 or gcc -m64: looks 
like
I used the latter and probably there was a good reason.

My
(superficial)  look at the readline docs didn't offer any advice in 
this
direction, nor did my googling produce any.

I realize that the real hidden message here is probably to accept
that it is time to make the transition to ESS, but I'm still resisting
this,

Um, you need a 64-bit emacs with readline for a 64-bit ESS ....

and hope that someone could suggest a way to get readline going.
