You can, but simply pick a more up-to-date mirror or the main CRAN site. FWIW the master server for Mac releases is

The simple fix is to switch to R BLAS instead of vecLib BLAS (see R for Mac FAQ 12.5). Alternatively update to R 2.13.2, the issue has been fixed in the CRAN binary distribution of R 2.13.2.
