If I remember right, php5-fpm is related to FastCGI (for PHP scripts). One again, LXR do not need it because it runs either as a [standard] CGI script or under mod_perl.
My site only contained a more or less vanilla Apache2 installation
before installing LXR.
I.E: "/var/www/html/index.html" and nothing more.
I did install phpbb5 and MediaWiki packages
I installed php5-fpm because some web site recommended this as a
solution to the problem.
It occured before that.

After "a2dismod php5" I could start the apache2 server without the error
message.
service apache2 restart

qualified domain name, using 127.0.1.1.
Set the 'ServerName' directive globally to suppress this message

The configuration process has created a thttpd-lxrserver.conf which you can find in custom.d/. Change or add a port=<port-number> directive to tell which port to listen to. See the comments in the file about the host directive and the directory and symbolic links to create. For more information, download the User's Manual and read section 1.8.e (taking care that you have two web servers running and you must give thttpd an id different from localhost or 127.0.0.1) or more thoroughly chapter 7 (more precisely 7.6 dedicated to thttpd).
