Update:
I got it working. My old code was as follows:

   def index(req, name='John'):
      s = 'Hello, there!'
      if name:
         names = ['a', 'b', 'c']
         s = 'Hello, %s!' % name.capitalize()
         tmpl = psp.PSP(req, filename='index.psp')
         tmpl.run(vars = { 'greet': s, 'names': names })
      return

Now I did this:

   def index(req, name='John'):
      s = 'Hello, there!'
      if name:
         names = ['a', 'b', 'c']
         s = 'Hello, %s!' % name.capitalize()
         tmpl = psp.PSP(req, filename='index.psp',
            vars = { 'greet': s, 'names': names })
      return tmpl

So basically I assigned the variables on instantiation of the PSP
object and returned the resulting reference. This is different to what
is noted at onlamp.com
