Dan, for OS X, there is a new pcre library posted at http://r.research.att.com/libs/ with a date stamp of Dec 28. This fixes this problem. You can test for this by running make check post compilation. It'll bang out with a failure if this is not in order.
(And I know that all of this is described in R-admin). It would be helpful (time saving) if a message is posted to r-sig-mac whenever a new (version of a) library is added to http://r.research.att.com/libs/ I know it is adding more work to the helpful people who are doing all the heavy lifting.
