I would try to download 3.0.1 from a different CRAN mirror. My first guess is that your download was corrupted and/or did not install correctly or fully.
You could try to test the MD5 hash for the downloaded file. The correct hash value is listed on the download page for OSX:
In a terminal:
MD5 (R-3.0.1.pkg) = c0e6e702742f17cd9b2f2e4cb1c5dcad
P.S. to Simon. Should there be a consideration for replacing MD5 with SHA, given the issues with the former?
