[Plugin: W3 Total Cache] Change path to mod_*

I’m using WP 3.2.1 and “W3 Total Cache” 0.9.2.4. The most functions working fine, but not all. The compatibility check says:

mod_deflate: Not detected
mod_env: Not detected
mod_expires: Not detected
mod_headers: Not detected
mod_mime: Not detected
mod_rewrite: Not detected
mod_setenvif: Not detected

My info.php tells me however:

Server Root: /usr/lib/sphereconf/apache

Loaded Modules: core mod_access mod_auth mod_include mod_deflate mod_log_config mod_env mod_expires mod_setenvif mod_ssl prefork http_core mod_mime mod_dav mod_status mod_autoindex mod_asis mod_suexec mod_cgi mod_dav_fs mod_negotiation mod_dir mod_imap mod_actions mod_userdir mod_alias mod_rewrite mod_so mod_proxy proxy_connect proxy_ftp proxy_http mod_php5

The mods the plugin is looking for are there, but how can I config this?
