OS X / macOS has had pcre 8.02 for years, and R has required at least 
8.12 for years.  (opensource.apple.com is currently broken, so I cannot 
check how many years.)

If all else fails, read the manual (§C.3):

'Those and other binary components are available from 
https://r.research.att.com/libs: you will need pcre and xz (for libzma) 
as recent macOS versions provide libraries but not headers for these 
(and the system pcre is too old at version 8.02).'

That build of pcre 8.36 is static, and so avoids any problems with 
dynamic load paths.  It is trivial to build later versions (statically) 
from the PCRE sources for yourself.
