+Use apt-get to make sure you have all that is required. A number
+of packages will get added through dependencies.
+
+ apt-get install libpango1.0-dev libxml2-dev

+=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
+flags: http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=2

+=head1 BUILDING DEPENDENCIES
+
+But again this may have been too optimistic still, and you actually have to
+compile your own copies of some of the required libraries. Things like
+libpng and zlib are pretty standard so you will probably have them on your
+system anyway. Freetype, Fontinst, Cairo, Pango may be installed, but it is
+possible that they are pretty old and thus don't live up to our
+expectations, so you may want to compile their latest versions.
