Install help for Kolab newbie

[Paul Waldo]

Hi all,

I have been trying to evaluate Kolab, without much success.  Before I 
moved to another groupware solution, I thought I'd try to get some help 
from the experts :-)

I'm running a Kubuntu Gusty AMD64 machine.  I first tried the kolab 
packages that came with the OS.  I successfully ran kolab_bootstrap, but 
now when I try to get initially logged in via the web admin interface 
(https://kolab.mydomain/admin/), I just get a blank page.  I've looked 
in the apache logs, but the only thing of note I see is
10.0.0.10 - - [30/Nov/2007:13:54:49 +0000] "GET /admin/ HTTP/1.1" 200 -
Not very interesting...
I'm not sure where to procede from her in debugging.  Ubuntu packages 
would be my preferred method of install, but just to be thourough, I 
figured I would try compiling from source.  This is on a Kubuntu 6.06 box.

I got all of the files from 
http://max.kde.org:8080/mirrors/ftp.kolab.org/server/release/kolab-server-2.1.0/sources/
I followed the instructions at 
http://wiki.kolab.org/index.php/Ubuntu_6.06 to get gcc 3.4
I followed the intructions at 
http://wiki.kolab.org/index.php/Kolab2_Installation_-_Source

Compilation fails like this:

Any help with either of these install scenarios would be greatly 
appreciated!  TIA.

Paul

PS
Is there a demo server that I can access just to see how kolab works?  
I'd hate to go through all this effort only to find that it doesn't fit 
my needs :-(
