Startup problems: subversion checkout failed

Hello everybody,
after some mess with our versioning system and the JUnit tests my boss 
ordered me to setup a continuous integration environment. So here I am. 
Installing and starting Anthill was pretty straight forward but then I 
got stuck.
I use Anthill OS version 1.8.1.303, Java 1.5.0_08, Subversion 1.4.0 and 
Tomcat 5.5.17 on a WinXP SP2 machine.
Whenever I try to build our project (manual build with "force build" 
option, "build as version" not set) Anthill is not even able to checkout 
the project from the subversion repository. I looked up the svn commands 
in the conf/profiles/Win32/win_subversion/getWorkingProject.pgl and ran 
them on the commandline - no problem, everything worked fine.
As there is no up-to-date documentation for the subversion-adapter I 
don't know where the problem is. The error messages from the Tomcat 
stdout_xxx.log didn't help either

All that I know now is that it failed to retrieve the code from the 
repository for whatever reason "error=2" refers to. Do I have to setup 
the version adapter before I am able to checkout code from the 
repository? I don't want to put files into the repository before I'm 
absolutely sure that I have to. There is quite enough garbage in there 
without me adding more. If I have to setup that version-stuff I would 
prefer to do that on my machine before using the repository. The 
"couldn't send result email" error is not a problem at the moment, I 
just haven't setup the mail-server yet.

I am thankful for any contributions to my problem.

Greetings

Sebastian
