On Apple Mac running OS X 10.11:

Downloaded ftp://alpha.gnu.org/gnu/emacs/pretest/emacs-25.0.90.tar.xz
Unpacked it.
Ran ./configure
Ran make
Compile stopped with:

  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

On my system, that file is found in:

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/libxml2/libxml

This may be related to:

2015-12-31 YAMAMOTO Mitsuharu <mituharu <at> math.s.chiba-u.ac.jp>

* configure.ac: Find libxml2 headers in Xcode SDK dir on Darwin.

I ran:

$ xcrun --show-sdk-path
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk

config.status has:

S["LIBXML2_LIBS"]="-lxml2 "
S["LIBXML2_CFLAGS"]="-I/usr/include/libxml2 "

> It appears that the libxml-2.0.pc file was installed when I used brew to install some package a few weeks ago. I renamed libxml-2.0.pc to something else and re-ran the configure and make and it built without error. I'm sorry for the false alarm and thanks for your assistance

Homebrew seems to require the installation of Command Line Tools for
Xcode.

  https://github.com/Homebrew/homebrew/blob/master/share/doc/homebrew/Installation.md

If you follow the above instructions, then /usr/include will be
created and the build of Emacs will succeed.
