go to www.ximian.com
you can download there a package called redcarpet. with that package, you have an automatic installer to evolution. redccarpet only works for some 2 disros, but you can also get evolution sources and binary packages (without redcarpet). The ximian connector package is completely unknown to me, cos I never needed ximian connector, but you can also download it from the ximian website.
I use evolution, because it is a complete and fine PIM it war really worth the ~5 hours compile time... :-)
