[Boost-users] [regex] link error on upgrade to 1.62.0

Hi, I'm trying to update from 1.60.0 to 1.62.0 on Mac with Xcode 4.6.3, and I'm getting link errors on Regex. I am definitely compiling all 17 of the .cpp files in libs/regex/src. The errors are shown below. Any idea what I might be missing? Undefined symbols for architecture i386: "boost::re_detail_106200::perl_matcher >, boost::regex_traits
