[GoogleCodeExporter]

What steps will reproduce the problem?

1.  patch util/util.h line46,47 to

#include <unordered_set>
using std::unordered_set;

2. make install prefix=/usr/local/Cellar/re2/20130802

Outputs:

clang: warning: argument unused during compilation: '-pthread'
Undefined symbols for architecture x86_64:
  "operator<<(std::ostream&, re2::StringPiece const&)", referenced from:
     -exported_symbol[s_list] command line option
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [obj/so/libre2.so] Error 1

What is the expected output? What do you see instead?

Without errors and build success.

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

Xcode 5, OS X 10.9

Remove the untangling of re2::StringPiece and it builds fine:
