Actually, there is a message in the output of ./configure:
R is now configured for i686-pc-linux-gnu
Source directory: .
Installation directory: /usr/local
C compiler: gcc -D__NO_MATH_INLINES -mieee-fp -g -O2
C++ compiler: g++ -mieee-fp -g -O2
Fortran compiler: g77 -mieee-fp -g -O2
Interfaces supported: X11, tcltk
External libraries: readline, BLAS(generic)
Additional capabilities: PNG, JPEG, bzip2, PCRE
Options enabled: R profiling
Recommended packages: yes
Note that in the above, the line "External libraries" indicates what
will be supported, which in my case, shows readline.
In addition, you can use capabilities() once in the R console to see
what has been included:
jpeg png tcltk X11 GNOME libz http/ftp sockets
TRUE TRUE TRUE TRUE FALSE TRUE TRUE TRUE
libxml fifo cledit IEEE754 bzip2 PCRE
TRUE TRUE TRUE TRUE TRUE TRUE
In the above case, 'cledit' shows TRUE, which is the indication that
command line editing is supported.
On your final thought, you might want to review the following:
