[Boost-users] [python] boost-python headers - are they python version specific?

I have python 2.7.3 and 3.2.1 deployed in my environment. I want to build 2 variants of boost python - one for each python version. My question is - will the boost headers be different; or can I just use the same header location for the boost headers, and link against a different boost-python library depending on which python version I want? TIA Steve
