+=head2 Gentoo
+
+In Gentoo installing rrdtool is really simple you just need to B<emerge
+rrdtool>. All dependencies will be handled automatically by the portage
+system. The only thing you should care about are USE flags, which allow you
+fine tune features rrdtool will be built with. Currently the following USE
+flags are available:
+
+ doc - install .html and .txt documentation
+ into /usr/share/doc/rrdtool-1.x.xx/
+ perl - build and install perl language bindings
+ python - build and install python language bindings
+ ruby - build and install ruby language bindings
+ tcl - build and install tcl language bindings
+ rrdcgi - build and install rrdcgi
+
+After you've decided which USE flags you need, set them either in
+F<make.conf> or F</etc/portage/package.use> and finally run:
+
+ # emerge -va rrdtool
+
+Take a look at Gentoo handbook for further details on how to manage USE
