upgrading to v4, change of "req.backend.healthy" -> "std.healthy(req.backend)" reports "Symbol not found: 'std.healthy' (expected type BOOL)"

I also just noticed that even though I configure with

...
--enable-pcre-jit --with-pcre-config=/usr/local/bin/pcre-config
...

and


/usr/local/bin/pcre-config --libs
  -L/usr/local/lib64 -lpcre

that the BIN links the SYSTEM libs

  libpcre.so.1 => /usr/lib64/libpcre.so.1 (0x00007fa946321000)

This seems like rpath'ing ...
