Equivalent setup of llvm-gcc-4.2-2.3 setup of *.dylib in README.LLVM for Ubuntu 8.04

I’m trying to setup the llvm-gcc-4.2-2.3 front end which I’ve built from source on Ubunutu 8.04.

It has built successfuly. In the README.LLVM file, it says that the following must be done after the “make install” step:

$ make install
$ ln -sf /usr/lib/libstdc++.6.dylib pwd/…/install/lib
$ ln -sf /usr/lib/libstdc++.6.dylib pwd/…/install/lib/libstdc++.dylib

*.dylib files are OSX specific. What is the equivalent setup step for Ubuntu 8.04?
