Indeed. Details below.

One recommendation Googling showed me was to change the location of 
DocumentRoot to a directory in my home directory. I created a directory 
www in my /home/rsteff and changed the entry in 
/etc/apache2/sites-available from

DocumentRoot /var/www

to

DocumentRoot /home/rsteff/www

After restarting Apache it now looks at the new directory.

That error went away but a new one came up. I added an href to a php 
file that simply calls phpinfo. When I click on that link I get this 
error message:

[Fri Nov 04 10:51:15 2011] [warn] Script "/home/rsteff/www/phpinfo.php" 
resolving to "/home/rsteff/www/phpinfo.php" not within configured docroot


I changed the entry in /etc/suphp/suphp.conf from

;Path all scripts have to be in
docroot=/var/www:${HOME}/public_html

to

;Path all scripts have to be in
docroot=/home/rsteff/www

Now the href runs phpinfo as expected.

Very much. Thanks.

I am curious about the form of the docroot line I changed in suphp.conf.
What is the significance of ":${HOME}" in that line?
