[mod_python] ImportError: No module named mptest

Hi folks,

I just started with and mod_python. I get stuck with the Error message
below. Any help would be appreciated.

I'm using Ubuntu 7.04, Lampp, Apache/2.2.4 (Unix), mod_python/3.3.1 and
Python/2.5.1

I followed the instructions to this point
[http://modpython.org/live/current/doc-html/inst-trouble.html]

testing with the script describet at the tutorial. Unregarded the
scripts content it reports this one:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
MOD_PYTHON ERROR

ProcessId:      14842
Interpreter:    'localhost'

ServerName:     'localhost'
DocumentRoot:   '/opt/lampp/htdocs'

URI:            '/test/mptest.py'
Location:       None
Directory:      '/opt/lampp/htdocs/'
Filename:       '/opt/lampp/htdocs/test/mptest.py'
PathInfo:       ''

Phase:          'PythonHandler'
Handler:        'mptest'

Traceback (most recent call last):

ImportError: No module named mptest
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Here is what I've put in the httpd.config file:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
LoadModule python_module /opt/lampp/modules/mod_python.so

<Directory /opt/lampp/htdocs>
	AddHandler mod_python .py
	PythonHandler mptest
	PythonDebug On
</Directory>

<Location /mpinfo>
      SetHandler mod_python
      PythonHandler mod_python.testhandler
</Location>
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I guess there must be any file named mptest but I can't find it ...

Thank you for your time
