This behavior is really strange and I tested it in the last 10 minutes.
CMake says:
boost libs: /usr/lib/libboost_system-mt.so

Compiling and linking with verbose reveals the link command:
/usr/bin/c++      CMakeFiles/test.dir/test.cpp.o  -o test -rdynamic 
-lboost_system-mt

But a ldd on test gives:
andreas[515:3]:ldd test
         linux-vdso.so.1 =>  (0x00007fff2fb4a000)
         libboost_system.so.1.46.1 => /usr/lib/libboost_system.so.1.46.1 
(0x00007f525e8c7000)
         libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x00007f525e5bd000)
         libm.so.6 => /lib/libm.so.6 (0x00007f525e33a000)
         libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00007f525e124000)
         libc.so.6 => /lib/libc.so.6 (0x00007f525ddc3000)
         librt.so.1 => /lib/librt.so.1 (0x00007f525dbba000)
         libpthread.so.0 => /lib/libpthread.so.0 (0x00007f525d99e000)
         /lib64/ld-linux-x86-64.so.2 (0x00007f525eaf5000)

I don't install, only build the executable.

Does anybody have an idea?
