Thanks for your time

When it says that it needs bison, it's talking about a program you need.

A quick google shows you can download an updated version from here:
http://ftp.gnu.org/gnu/bison/

./configure is checking whether you have GNU Bison version 2.1.

You have to install GNU Bison 2.1 to successfully install this software.
