Moved to R-devel: please see the posting guide.  This WAY off topic for 
R-help.

Please do read the installation manual:  configure --help says

   --with-readline         use readline library (if available) [yes]

and note, no path can be specified.  The installation manual says

   If you have libraries and header files, e.g., for GNU readline, in
   non-system directories, use the variables LDFLAGS (for libraries, using
   `-L' flags to be passed to the linker) and CPPFLAGS (for header files,
   using `-I' flags to be passed to the C/C++ preprocessors), respectively,
   to specify these locations. These default to LDFLAGS=-L/usr/local/lib
   (/usr/local/lib64 on most 64-bit Linux OSes) and
   CPPFLAGS=-I/usr/local/include to catch the most common cases.

My guess is that you need something like

CPPFLAGS=-I/usr/local/include -I/home3/fa/faga001/vol/readline-5.1/include
LDFLAGS=-L/usr/local/lib -L/home3/fa/faga001/vol/readline-5.1/lib

If this really is readline-5.1, don't use it.  It needs a patch (I believe 
the one found on the GNU mirror suffices) or it is badly broken, enough to 
crash the calling application.
