Patch

When compiling ns-3 on Mac (Mountain Lion) with Mac ports g++ version 4.7 I encountered the following error:

16:11:40 runner ['g++-mp-4.7', '-O0', '-ggdb', '-g3', '-Wall', '-Werror', '-Wno-error=deprecated-declarations', '-fstrict-aliasing', '-Wstrict-aliasing', '-fPIC', '-compatibility_version', '1', '-current_version', '1', '-I.', '-I..', '-DNS3_ASSERT_ENABLE', '-DNS3_LOG_ENABLE', '-DHAVE_SYS_IOCTL_H=1', '../src/fd-net-device/model/fd-net-device.cc', '-c', '-o', 'src/fd-net-device/model/fd-net-device.cc.1.o']

According to http://en.cppreference.com/w/cpp/string/byte/strerror the std::strerror is defined in <cstring> which was not included in the creator-utils.cc file. 

Adding the include fixed the problem, see attached patch.

All the best,
