I think that is an unrelated problem on your system. See:

 http://stackoverflow.com/questions/3907719/how-to-fix-tar-failed-to-set-default-locale-error

But if you didn't get any other error the installation might have
succeeded? Try loading the package:

  library(pdftools)

If that works you might be OK.
