Installing apache on suse is quite easy if you use the apache rpms that come with it. The only tricky part (if you've never done that) is probably going to be configuring apache in such a way that you can easily write & run cgi scripts from your development directory (probably in your homedir).

I've got the following entry in my (apache 1.3) configuration:

# 
# UserDir: The name of the directory which is appended onto a user's h
+ome
# directory if a ~user request is received.
#
<IfModule mod_userdir.c>
    UserDir public_html
#
# Control access to UserDir directories.  The following is an example
# for a site where these directories are restricted to read-only.
#
    <Directory /home/*/public_html>
        AllowOverride All
        AddHandler perl-script .cgi
        Options All +ExecCGI
        <Limit GET POST OPTIONS PROPFIND>
            Order allow,deny 
            Allow from all
        </Limit>
        <Limit PUT DELETE PATCH PROPPATCH MKCOL COPY MOVE LOCK UNLOCK>
            Order deny,allow
            Deny from all
        </Limit>
    </Directory>
</IfModule>

Which means that every user's "public_html" directory in their homedir is accessible as http://localhost/~username/ and that files ending in .cgi will be run as cgi scripts.
