Description of problem:

With FDS 1.0.2 (and likely all versions) on Ubuntu Dapper Drake the adminserver
setup program is unable to find the Apache modules.

-------

From the fedora-directory-users mailing list:

Running it interactively (on Debian and Ubuntu) and then choosing the '2 -
Typical' install mode) one comes to the point the installer tries to locate the
Apache modules, then it returns:

Unable to locate Apache modules in
/modules
.
Press any key to continue. 

In fact, the Apache modules are here on the system:

root@helix:/opt/fedora-ds/setup# ls -lsa /usr/lib/apache2/
total 28
 4 drwxr-xr-x  3 root root     4096 2006-06-15 11:05 .
 8 drwxr-xr-x 38 root root     8192 2006-06-15 12:02 ..
 4 drwxr-xr-x  2 root root     4096 2006-06-15 11:05 modules

However if one adds 'ApacheRoot=   /usr/lib/apache2' to the [admin] section of
an install.inf and one runs a silent install afterwards, there seems to be no
problem.

-------

Now the setup program runs httpd -V in and uses the value of HTTPD_ROOT to
determine where the modules are. This doesn't work on Debian systems,
apparently. The output on Dapper is:

root@helix:/opt/fedora-ds# httpd -V
