Let us know (which you have).  This appears to be a lack of POSIX 
compliance on FreeBSD (even POSIX 2004, the current link being 
http://pubs.opengroup.org/onlinepubs/9699919799/functions/getrlimit.html), 
so was unexpected and you ought to file a FreeBSD bug report.

I'll add a workaround in R-devel in r72147: let us know if that does not 
suffice.
