Well then install the bison package. Its in main so if you haven't setup your sources properly go to http://easyurpmi.zarb.org
However since this is a newbie forum I'll assume you just want to use Evolution, not compile it. In that case just install the package 'evolution' (in the software installation thingo in the Mandriva Control Centre) and you'll see it on your menu after a short delay. There's no need to go downloading source code from websites and try to install it if all you want to do is use the program.
