[Zope] which python gets used ... ?

Hi, just a quickie idiot question .. Does zope use any of the python on my RH6.2 box or does it use its own copy exclusively? I was trying to install the python xml libraries to try our the hyperdom product. I installed an rpm succesfully before remembering that zope has its own python. I struggled to install a tgz version though and it struck me that I was probably not being as efficient as I could be ... So the question is: can I run zope using the stock RH6.2 distributions' own copy of python? cheers Jonathan
