Thanks for the hint!

In configure.ac:

   xcsdkdir=`$XCRUN --show-sdk-path 2>/dev/null`
   [...]
   LIBXML2_CFLAGS="-I'$xcsdkdir/usr/include/libxml2'"

My $XCRUN is empty (I don't know why), therefore, in src/Makefile:

   LIBXML2_CFLAGS = -I/usr/include/libxml2

But I don't even have the /usr/include/ directory.  With GNU findutils
(find / -regex '.*xml.*') I found that libxml2 is in
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include,
instead of /usr/include/.

What should I do now?  `sudo ln -s' looks like an ugly hack.  Any suggestions?
