This error message is an important clue, but I'm not sure where it
leads. It could indicate a problem with your system or your R
installation.
Try asking at R-SIG-Mac <r-sig-mac at r-project.org>. Meanwhile, try
setting different values for options(download.file.method = ...) before
attempting package installation. Perhaps one of the available options,
which include "internal", "libcurl", "wget", "curl", would work.
