[R] readline with R-1.4.0

[apjaworski@mmm.com]

Hi,

I am not sure if this is a bug, so I am posting it here.  I also searched
the FAQ file for the readline string and did not find anything about the
behavior below.

I just successfully rsync'ed, compiled and tested R-1.4.0 on my RH 7.2
Linux machine.  I encountered one problem though.  When running ./configure
I noticed that I was getting errors from the readline library.  Although
configure detected readline, the internal test it runs failed.  Now, my RH
distribution has readline version 4.2-2 (both dynamic and static).  It also
contains the older version for compatibility purposes.  In /usr/lib I have

     libreadline.a                       (static 4.2-2)
     libreadline.so.4.2            (dynamic 4.2-2)
     libreadline.so.3.0            (dynamic 2.2.1 !?)
     libreadline.so -> libreadline.so.4.2     (symbolic link)

This setup created the failure I just mentioned.  However, when I changed
the link to

     libreadline.so -> libreadline.so.3.0

everything went fine with configure and compilation.  The odd thing is that
after compilation finished I changed the above symbolic link back to
libreadline.so.4.2 and all tests ran with no problem.  Readline also seems
to work in interactive mode.
