OK, so you need to change the install name of your libc++abi.dylib.

1. Copy or move the downloaded `libc++abi.dylib` to `SOME_PATH/libcxx/lib`.
2. `cd SOME_PATH/libcxx/lib`
3. Change the install name:
    install_name_tool -id SOME_PATH/libcxx/lib/libc++abi.dylib libc++abi.dylib

(Actually you don't need to copy `libc++abi.dylib` to `SOME_PATH/libcxx/lib`.
In that case, the command for changing the install name is:
    cd /home/kbelco/libcppabi
    install_name_tool -id /home/kbelco/libcppabi/libc++abi.dylib libc++abi.dylib
Then, add `/home/kbelco/libcppabi` to <linkflags> and DYLD_LIBRARY_PATH.)

As for `/usr/lib/libSystem.B.dylib`, I believe it is installed by default
on Mac OS X 10.6.
