[mod_python] Can't get mod_python's PSP 'Hello World' to work

I've been having difficulty configuring my Debian server to use PSP as
a templating system. Since I lack the verbage and expertise to explain
what I have/haven't done, I've made a webpage with snapshots outlining
the problem:

Any ideas?
