Error installing kolab 2.2 on debian

[Rene Ouderling]

Hi,

Yesterday i installed KOLAB 2.2 on a testsystem with Debian etch 4.04. The 
installation finished without a problem.  specification (uname -a) of the 
test system: Linux xxxx 2.6.18-6-686 #1 SMP Thu Oct 9 15:52:18 UTC 2008 i686 
GNU/Linux.

Today I want to install Kolab 2.2 (with openpkg) on a virtual server also 
running debian. Specs of the server (uname -a) Linux xxxxxxxxxx 
2.6.26-1-amd64 #1 SMP Thu Oct 9 14:16:53 UTC 2008 x86_64 GNU/Linux

After following the procedure and installing the nessesary programs like make, 
gcc, flex, bison, libtool, automake and autoconf I am getting an error during 
compilation.

Has anyone an idea what is wrong.

Kind regards
