boost::asio::streambuf -- linker error

I'm having trouble getting a boost program to compile. The example I'm trying to compile is here: http://rosettacode.org/wiki/Web_scraping#C.2B.2B

This is what happens when I try to compile:

  % g++ -Wall test.c -lboost_regex  -lboost_system -lboost_thread 
    /tmp/ccJSxOji.o: In function `boost::exception_detail::error_info_injector<std::length_error>::error_info_injector(boost::exception_detail::error_info_injector<std::length_error> const&)':
    test.c:(.text._ZN5boost16exception_detail19error_info_injectorISt12length_errorEC2ERKS3_[_ZN5boost16exception_detail19error_info_injectorISt12length_errorEC5ERKS3_]+0x53): undefined reference to `std::length_error::~length_error()'
    /tmp/ccJSxOji.o: In function `boost::exception_detail::error_info_injector<std::length_error>::~error_info_injector()':
    test.c:(.text._ZN5boost16exception_detail19error_info_injectorISt12length_errorED2Ev[_ZN5boost16exception_detail19error_info_injectorISt12length_errorED5Ev]+0x2e): undefined reference to `std::length_error::~length_error()'
    collect2: ld returned 1 exit status

I think I've narrowed the problem down to this line:

boost::asio::streambuf response ;

I'm using gcc 4.6.0, linux of course:

I hate to answer my own question, but as it turns out, I was bitten by this: /usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.15' not found

I did some more digging:

 % ldd /usr/lib/libboost_regex.so
/usr/lib/libboost_regex.so: /usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.15' not found (required by /usr/lib/libboost_regex.so)

        /lib/ld-linux.so.2 (0xb78d0000)

In sum, my gcc-libs were out of date. To fix it, I did:

# pacman -Q -o /usr/lib/libstdc++.so.6
/usr/lib/libstdc++.so.6 is owned by gcc-libs 4.6.0-5

# pacman -S gcc-libs

Thanks to everyone who commented, you got me thinking in the right direction.
