[Zope] Xron: installation problem

[Pascal FITTON]

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
