 pkg-config --libs libxml-2.0
 displays "Libs.private field occurs twice in
 '/opt/local/lib/pkgconfig/libxml-2.0.pc'" with the universal variant of
 libxml2 installed on Snow Leopard.

 The libxml-2.0.pc file contains:

 #ifndef __LP64__
 Libs.private: -lpthread   -liconv -lm
 #else /* __LP64__ */
 Libs.private: -lpthread -lz  -liconv -lm
 #endif /* __LP64__ */

 and the preprocessor directives are evidently confusing pkg-config.
