Apple overlooked something.  The pkg-config you are using is not 
provided by Apple, and Apple does not provide pkg-config files for the 
software it provides[*] where installing from sources would do so.

I do have a /usr/local/lib/pkgconfig/libxml-2.0.pc, containing

prefix=/usr
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include
modules=1

Name: libXML
Version: 2.9.1
Description: libXML library version2.
Requires:
Libs: -L${libdir} -lxml2
Libs.private:  -lpthread -lz  -liconv -lm
Cflags: -I${includedir}/libxml2

from a source installation of libxml2.

[*] Strangely, /usr/lib/pkgconfig is not quite empty on my box.
