Linker error involving boost_lock

Question

I'm working on a game engine http://ducttape-dev.org that uses boost as one of the dependencies. One day, as I was writing a test app that linked to my game engine, the Extruder of OgreProcedural threw this type of liker error. After troubleshooting and googling for a couple hours, I did a system update (I'm running archlinux) and rebuilt all the dependencies. Rebooted, still got same kind of error. Tried to rebuild the engine, and got the linker error. Every time I try to link the engine, it throws this error http://pastebin.com/PGH25Yuy.

this just happened to be on libMyGUI, but I gotten it referencing files in the engine instead, and all in the format of "(error stuff) referenced in section (more error stuff) [non virtual thunk to (some file) of (some file) defined in discarded section (some file)". I can build MyGUI from source and get no errors, I can build boost from source and get no errors. I don't know how to troubleshoot this. I don't even know what this means. Any help (even if you could just tell me what kind of error this is) would be greatly appreciated.

archlinux x64, amd64 athlon x2, 5Gb RAM, gcc 4.6.2, binutils 2.21.1, boost 1.47.0

Previously I had a similar error after updating to gcc 4.6.2. The weird thing was that downgrading of all packages (gcc, libtool, boost) did not fix the problem. The problem appears to be a mixed compilation: I reupgraded all packages (newest versions of repo) then threw away old compilation data (make clean) and rebuilt the whole thing. Then it worked.

Here the similar error I got:
