Project doesn't make

[GoogleCodeExporter]

What steps will reproduce the problem?
1. make third_party
2. make all
3.

What is the expected output? What do you see instead?
I expect that after successfully compiling third_party, I don't get such error 
"fatal error: gflags/gflags.h: No such file or directory
 #include "gflags/gflags.h"".

What version of the product are you using? On what operating system?
r3869

Please provide any additional information below.

Hi, 

can you try with the github version?

If you mean github version of gflags then release-2.1.1 and copy of master 
brunch doesn't work for me.
P.S. Excuse my bad English.

No, I meant the copy of or-tools from github instead of code.google.com.

Thank you. It works for me. I'd like to ask one more question about bin/fz.
I have quad core processor(2 physical cores). But when I run fz with flag 
-workers with value 4, fz works rather slower than faster. Is there a some 
guarantees that multi-threaded version will be faster in the average case? Some 
tests show that multi-threaded version is slower in several times. One example 
is attached.
