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:

#include <libxml/tree.h>
         ^
1 error generated.
make[1]: *** [xml.o] Error 1

On my system, that file is found in:

* 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:

What's the output of "pkg-config --cflags 'libxml-2.0 > 2.6.17'" ?
Do you have the directory /usr/include ?

$ pkg-config --cflags 'libxml-2.0 > 2.6.17'
-I/usr/include/libxml2

/usr/include does not exist per se. Instead, it is:

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

I tried to create a soft link:

$ sudo ln -s /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include /usr/include
Password:
ln: /usr/include: Operation not permitted

Apple no longer allows such things.

This means libxml-2.0.pc in your installation of libxml2 is bogus.
IIUC, Apple does not provide us with libxml-2.0.pc in their SDK, so
probably you should have installed libxml2 on your own.

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.

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
