[Zope] Xron: installation problem

Hi! when i take the Xron (v0.0.9) file, i untar and place it into the zope directory. I restart Zope and i give my username and password but after i can't see the windows manager.... i'll see the Xron's files and i think that files can't be compiled.... I've been installed python 1.5.2, python-devel, and i use the Zope zserver. If somebody know how i can do to succeed to install it. thanx pascal
