[R] readline, 64bit solaris build

I've built a 64bit version of R 1.9.1 on a solaris 2.9 sparc system.  
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: warning: file /usr/local/lib/libreadline.a(callback.o): wrong ELF
> class: ELFCLASS32
> Undefined                       first referenced
>  symbol                             in file
> rl_callback_read_char               conftest.o
> ld: fatal: Symbol referencing errors. No output written to conftest
> configure:21313: $? = 1
> configure: failed program was:
> | /* confdefs.h.  */

in config.log...  do I interpret this correctly  as a gentle suggestion 
readline should be remade as a 64bit library?  Can this be done?  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 
and hope that someone could suggest a way to get readline going.
