[R] deficiencies in readline capability

When I first configured and built R, I did not have the GNU readline
library installed on my system, so naturally I got an R without
readline capabilities. I then installed the GNU readline library, and
again configured and built R. I now have an R with readline
capability, but it is a deficient readline capability, providing only
one-line editing capability (e.g., CTRL-A, CTRL-E, CTRL-B, CTRL-F,
CTRL-D) without any history functionality (e.g., CTRL-P, CTRL-N,
CTRL-R). The shared libraries, version, and history capability of R
are as shown in the following logfile, where "$ " is my shell prompt:
$ ldd /opt/jay/lib/SunOS5/R/bin/R.bin
libm.so.1 => /usr/lib/libm.so.1
libz.so => /opt/jay/lib/SunOS5/libz.so

libsocket.so.1 => /usr/lib/libsocket.so.1

Error in savehistory(file) : no history available to save
Clearly I am using the GNU readline libraries, but there is another,
and perhaps unrelated, problem, which is that no history is
accessible. I gave R no configuration option to turn off history
capability when I configured it, nor am I aware that any such option
What am I doing wrong?
