+B<configure> complaining about several missing libraries.
+
+=head1 INSTALLING DEPENDENCIES
+
+If your OS lets you install additional packages from a software repository,
+you may get away with installing the missing packages. When the packages are
+installed, run configure again and try to compile again. Below you find some
+hints on getting your OS ready for the rrdtool compilation.
+
+Additions to this list are welcome.
+
+=head2 OpenSolaris 2008.05
+
+Just add a compiler and the gnome development package:
+
+ pkg install sunstudioexpress
+ pkg install SUNWgnome-common-devel
+
+There is a problem with F<cairo.pc> on opensolaris. It suggests that
+xrender is required for compilation with cairo. This is not true and also
+bad since opensolaris does not include an F<xrender.pc> file. Use perl to
+fix this:
+
+ perl -i~ -p -e 's/(Requires.*?)\s*xrender.*/$1/' /usr/lib/pkgconfig/cairo.pc
+
+Make sure rrdtool finds your new compiler
+
+ export PATH=/opt/SunStudioExpress/bin
+
+Since there does not seem to ba a viable msgfmt tool on opensolaris (short
+of installing it yourself). You have to call configure with the
+
+ --disable-libintl
+
+option.
+
+=head2 Debian / Ubuntu
+
+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.
+
+=head2 General build tips for AIX
+
+If you are working with AIX, you may find the the B<--disable-shared> option
+will cause things to break for you. In that case you may have to install the
+shared libraries into the rrdtool PREFIX and work with B<--disable-static>
+instead.
+
+Another hint to get rrdtool working on AIX is to use the IBM XL C Compiler:
+
+ export CC=/usr/vac/bin/cc
+ export PERLCC=$CC
+
+(Better instructions for AIX welcome!)
+
+=head2 Build Instructions
+
+Some libraries want to know where other libraries are. For this to work,
+set the following environment variable
