Looking at the output that the OP has provided implies to me that she used the makecdfenv package to create a cdf package, but installed it incorrectly. Dorothy - you did everything correctly up until the last step. You have to use R CMD INSTALL to install any package, whether or not it has a .tar.gz suffix (which you could make using R CMD build, but this is not necessary). So just move the folder back out onto e.g., your desktop and then install.
