As long as you install the new 3.3 build in a custom path (via  
--prefix) it will not overwrite your current installation and by  
default python3.3 will invoke the standard installation (probably in  
your /usr directory).
To use your custom build in virtualenvs make sure you create the  
virtualenv with the python interpreter of that build (the one in the  
<prefix>/bin directory). Your virtualenv will link to this  
installation and when your virtualenv is active, python3.3 will invoke  
the interpreter from your own build.

I hope this explaination is understandable (and correct), if not just  
ask. When using virtualenvs the first time I found it very confusing,  
too.
