You should start by getting the latest Xcode for OS X 10.9, v6.2 (with Apple LLVM version 6.0 (clang-600.0.57) (based on LLVM 3.5svn)) from here:
https://developer.apple.com/downloads/
(direct link: http://adcdownload.apple.com/Developer_Tools/Xcode_6.2/Xcode_6.2.dmg)
(you may need to sign up for a free developer account to get access to this download).

What version of kactivities is that? I have 4.13.3 installed through MacPorts.

I have boost 1.56.0, built without support for single-threaded libraries but that shouldn't be what makes the difference here, and the lines in the files cited above are identical in 1.56.0 as in 1.57.0 .

Two possibilities why I have not encountered this issue:
- you may need to enable C++11 mode explicitly (but I don't see that done by the MacPorts version)
- you may need to disable building the activityranking plugin, as MacPorts does.

HTH,
