Hi,

should this also work on MacOS X 10.11? Because I still get:

CC       xml.o
xml.c:23:10: fatal error: 'libxml/tree.h' file not found
#include <libxml/tree.h>
         ^
1 error generated.
make[1]: *** [xml.o] Error 1
make: *** [src] Error 2

It works if I use

CPPFLAGS='-I/usr/local/Cellar/libxml2/2.9.3/include/libxml2' and
LDFLAGS='-L/usr/local/Cellar/libxml2/2.9.3/lib'.

or

CPPFLAGS='-I/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/libxml2'
