I format my server and reinstall apache with apt-get install and perl and php5.
But when I do a2enmod, I don't have all modules I want but just :
actions asis auth_anon auth_dbm auth_digest auth_ldap cache ce rn_meta cgid cgi dav_fs dav deflate disk_cache expires ext_filter file_cache hea ders imap include info ldap mem_cache mime_magic perl php5 proxy_connect proxy_ftp proxy_http proxy rewrite speling ssl suexec unique_id userdir usertrack vhost _alias
With a manual install of apache.
for ssl, i've already install openssl but apache doesn't know where he has to find them ( that the pb I think)
