[Zope] newbie zope X3 3.0.0 trouble

[Neal Becker]

Newbie here:

I just tried zope X3 3.0.0 on linux FC3 python 2.3.4:
make install
/usr/bin/python install.py -q build
/usr/bin/python install.py -q install --skip-build --home
"/usr/local/ZopeX3-3.0.0"
[nbecker at nbecker ZopeX3-3.0.0]$ /usr/local/ZopeX3-3.0.0/bin/mkzopeinstance
-u xxx:yyy /usr/local/ZopeX3-3.0.0/home
Could not locate Zope software installation!

What's wrong?
