Rerun autogen.sh.

thanks, looks like it worked.
however, autogen.sh complained :

sed: -: No such file or directory

We should not be seeing this problem at all on Darwin, as lib/Makefile.am's 
include directive is protected inside an 'if BUILDING_FOR_WINDOWSNT'.... Oh, I 
see, the problem is that we are using a Automake conditional -- these days we 
assume GNU make so this should just be an ordinary GNU make conditional, which 
would have avoided the problem.

Anyway, I installed the attached patch to work around the immediate issue; 
please give it a try.

Subject: [PATCH] Port recent autogen.sh changes to Darwin

Problem reported by Sam Steingold (Bug#25347).
* autogen.sh: Don't assume 'sed -f-' reads a script from stdin, as
POSIX does not require it and it does not work on Darwin.

I faced this problem too.

Running autogen.sh first fixed the problem.

I believe Paul already fixed this.
