[Boost-users] [regex] link errors on 1.60 update

When I tried to convert my project from Boost 1.58.0 to 1.60.0, I got some link errors. This is using Xcode 4.6.3 on Mac OS X 10.7.5. I'm compiling all the sources in libs/regex/src. Help? Undefined symbols for architecture i386: "boost::re_detail_106000::perl_matcher >, boost::regex_traits
