 Hi there,

 I installed boost with MacPorts, most library works perfectly except
 boost::regex. Here is the informations from my dev environment:

 $ uname -a

 Darwin Kernel Version 13.1.0: Wed Apr  2 23:52:02 PDT 2014;
 root:xnu-2422.92.1~2/RELEASE_X86_64 x86_64

 $ sudo port installed | grep boost

 boost @1.55.0_2+no_single+no_static+python27 (active)

 here is the source code, quite simple:

 $ cat test.cpp

 #include <sstream>
 #include <iostream>

 #include <boost/regex.hpp>

 int main (int argc, const char* argv[])
 {
     boost::regex exp("*");
     boost::regex_match("foo", exp);
 }

 $ g++ --version

 $ g++ -std=c++11 -o test -I/opt/local/include -L/opt/local/lib
