 There is only one PCRE library (see http://www.pcre.org/) and you do need
to build it. What surprises me is that you must already be having its
headers (otherwise compilation would have failed before), so you probably
already downloaded it, didn't you?

 FWIW PCRE is very simple to build, it's just a bunch of .c files. Not
being C++ it can be built with any compiler, even g++ if it is simpler.

 Alternatively, you can always set HAVE_PCRE to 0 in your swigconfig.h if
you don't need this functionality.
