[Koha] Error on Koha web installer

[Leila]

Hello,
I have installed Koha 3.4.6 on Ubuntu 10.04 using
http://git.koha-community.org/gitweb/?p=koha.git;a=blob;f=INSTALL.ubuntu.lucid;hb=HEAD
Now that the Koha is actually opening when I try to work my way through the
webinstyaller I get the following message.

Undefined subroutine &main::setlanguagecookie called at
/usr/share/koha/intranet/cgi-bin/installer/install.pl line 25.


Help?!

Much thanks in advance

> Leila
