synaptic reinstalls old versions

[n dhert]

Ubuntu 9.04(jaunty).
I previously installed Verilog via the Synaptec Package Mgr, (latest version
0.8.6.1).
I want to install the newer version of that package (0.9.1)
Did a Complete removal of Verilog from Synaptec P.Mgr.
Then followed http://iverilog.wikia.com/wiki/Installation_Guide

$ sudo gedit /etc/apt/sources.lst
