apache & suexec & mod_fcgid & mod_userdir

[centurianii]

After following Falco's tutorial I managed to have working virtual hosts one per file.
Now, I want to access a user's home from the following url: http://www.example.com/~john/info.php with the help of mod_userdir.
Is this possible with suexec?

Let's see how john is configured at: /etc/apache2/sites-available/

#default virtual host
<VirtualHost *:80>
  ServerName www.john.example.com
  ServerAlias john.example.com
  ServerAdmin webmaster@john.example.com
  DocumentRoot /var/www/john/web/
  SuexecUserGroup john john
  <Directory /var/www/john/web/>
    Options +ExecCGI
    Options -Indexes
    AllowOverride All
    AddHandler fcgid-script .php
    #FCGIWrapper /var/www/php-fcgi-scripts/john/php-fcgi-starter .php
    FcgidWrapper /var/www/php-fcgi-scripts/john/php-fcgi-starter .php
    Order allow,deny
    Allow from all
  </Directory>

  # ErrorLog /var/log/apache2/error.log
  # CustomLog /var/log/apache2/access.log combined
  ServerSignature Off

</VirtualHost>

As you can see directive

SuexecUserGroup john john

is indeed a problem but as Apache states (http://httpd.apache.org/docs/2.2/suexec.html#usage):
"Requests that are processed by mod_userdir will call the suEXEC wrapper to execute CGI programs under the userid of the requested user directory."

I tried to modify file john (after enabling mod_userdir) to work for any user as follows:

<VirtualHost *:80>
  ServerAlias *.example.com
  ServerAdmin webmaster@example.com

  ##################
  ### solution ###
  ##################
  #mod_userdir directives for requests: http://www.example.com/~user
  UserDir disabled root
  UserDir /var/www/*/web

  #reduntant if using requests: http://www.example.com/~user
  #SuexecUserGroup john john
  <Directory /var/www/*/web/>
    Options +ExecCGI
    Options -Indexes
    AllowOverride All
    AddHandler fcgid-script .php
    #move to .htaccess
    #FCGIWrapper /var/www/php-fcgi-scripts/*/php-fcgi-starter .php
    #FcgidWrapper /var/www/php-fcgi-scripts/*/php-fcgi-starter .php
    Order allow,deny
    Allow from all
  </Directory>

  # ErrorLog /var/log/apache2/error.log
  # CustomLog /var/log/apache2/access.log combined
  ServerSignature Off

</VirtualHost>

As you can see I also created a .htaccess file with the directive:

FcgidWrapper /var/www/php-fcgi-scripts/john/php-fcgi-starter .php

(there is no meaning to keep * now in the path for wrapper script) but the result is for Apache to send the .php file info.php for download with no error logs!?

Any idea how to achive this?
Thanks.
