CGIwithR apparently is not available on CRAN for R 2.15.x, so I
downloaded the source (0.73) and tried:
~/Downloads$ R CMD INSTALL CGIwithR
Typo. Actually, I downloaded 0.72. Later, I found 0.73 here:
http://cran.r-project.org/src/contrib/Archive/CGIwithR/
D/L 0.73
tar -xzvf CGIwithR_0.73-0.tar.gz
R CMD INSTALL CGIwithR

After the installation of this R package is complete
copy the files R.cgi and .Rprofile in
/home/rex/R/x86_64-pc-linux-gnu-library/2.15/CGIwithR/cgi-bin/
to the cgi-bin area of your Web server. If necessary,
modify the settings in the first part of R.cgi to
suit your local configuration.

R.cgi
#! /bin/sh
### A shell script to make CGI scripting possible in R. Part of the
### "CGIwithR" package for R.
###
### Author: David Firth, University of Warwick
### (d.fi...@warwick.ac.uk)
###
### Terms of use: GPL version 2 or later. See "COPYING" in the
### R distribution.
###
### NO WARRANTY GIVEN, AND NO LIABILITY ACCEPTED FOR LOSS CAUSED BY
### USE OF THIS PROGRAM
###
###
### INSTALLING IT:
###
### This file, and the one-line ".Rprofile" file included with the
### package, must be placed together in a "cgi-bin" directory. Both
### files should be readable (and this file executable) by the web
### server.
###
###
### CONFIGURING IT:
###
### First locate R on the local system (typically the answer
### to "which R"). This is the command to run R.
### Individual R CGI scripts may request execution by a
### different, elsewhere-installed version of R; the R specified
### here is the default.
R_DEFAULT=/usr/bin/R
#R_DEFAULT=/usr/local/bin/R
### Graphs can be included in the output using either the
### GDD package (available from cran.r-project.org)
### or via ghostscript.
### GDD is the default. If it is not installed, the webPNG()
### function will attempt to use ghostscript. You can specify
### where the executable is located on your system via the R_GSCMD
### environment variable. If using GDD, you can ignore this.
R_GSCMD=/usr/bin/gs
#R_GSCMD=/usr/local/bin/gs
export R_GSCMD
### The next two lines may optionally be edited to limit access
### to local resources.
###
### This line allows specification of the priority
### given to the R process. A nice of "0" is the normal
### priority, while e.g. "+10" causes R to be run as a
### low-priority process. The value "NONE" should be given if
### nice is not implemented locally.
R_NICE=NONE
### This line allows the imposition of a length limit on the data
### entered on an HTML form for processing by an R script.
### Setting MAX_DATA_LENGTH=1000, for example, aborts
### execution if the data length exceeds 1000 characters. Or
### use MAX_DATA_LENGTH=NONE to impose no limit here.
MAX_DATA_LENGTH=1000
###
### To make use of packages not installed in the default library for R
### i.e. `R RHOME`/library/, set the environment R_LIBS to identify
### one or more library directories containing the packages (separated by :).
### This is only necessary if the CGIwithR package itself is not located
### in the default library, e.g. if one is using a different version.
R_LIBS=/home/rex/R/x86_64-pc-linux-gnu-library/2.15/
export R_LIBS
### No further configuration is needed.
No changes made in R.cgi below here.

If at first you do succeed, try not to look astonished.
