You should be aware that symbol versioning does not do this on solaris.

the notion of a library being able to export symbols with the same name and 
different versions pointing at different addresses is a gnu LD extension 
(<http://www.linuxshowcase.org/2000/2000papers/papers/browndavid/browndavid_html/>. 
section 4.1 discusses the capabilities of sun and gnu LD. section 4.2 
explains sun's versioning policy, and why they don't need the 
multiple-versions capability: once a function is considered 'public', sun 
never changes its function signature)
