I've probably installed them with rpm -i --force so it installed the new 
version, overrided libc.so.6,... but didn't
remove old libc.so.2.1.... files.

It's not a very good method but I haven't a better one.

I think you can use LD_LIBRARY_PATH to specify the directory containing your 
old libraries:
Create a diectory, put the old libraries in  it and call your programe like 
that:
        LD_LIBRARY_PATH=TheDirectory ./theProgram
I don't know exactly the action of this variable... I think it tell which 
directory to search first for libraries
