+ dencies for the specified plugin are not met. In that case you can force the
+ plugin to be built using the `--enable-<plugin>=force' configure option.
+ This will most likely fail though unless you're working in a very unusual
+ setup and you really know what you're doing. If you specify the
+ `--disable-<plugin>' configure option, the plugin will not be built. If you
+ specify the `--enable-all-plugins' or `--disable-all-plugins' configure
+ options, all plugins will be enabled or disabled respectively by default.

By default, collectd will be installed into `/opt/collectd'. You can adjust
this setting by specifying the `--prefix' configure option - see INSTALL for
