kolab 2.3.4 installation problem on openSuSE 12.1 x64

[Manuel]

Hello,

I've tried to install kolab-server-2.3.4 on openSuSE 12.1 64bit.
The compile tasks finished successfull. But I got an error in the 
section 'INSTALL: Installation of RPM':

mkdir /tmp/openpkg-20071227-root/kolab/var/lib
mkdir /tmp/openpkg-20071227-root/kolab/var/lib/openpkg
ln: failed to create symbolic link 
`/tmp/openpkg-20071227-root/kolab/lib64/openpkg/rpmt': No such file or 
directory
make[2]: *** [install-data-local] Error 1
make[2]: Leaving directory `/tmp/openpkg-20071227/rpm-4.2.1'
make[1]: *** [install-am] Error 2
make[1]: Leaving directory `/tmp/openpkg-20071227/rpm-4.2.1'
make: *** [install-recursive] Error 1
+ exit 2
./openpkg.boot:ERROR: script returned non-null value

I've attached the full log.

The directory /tmp/openpkg-20071227-root/kolab/lib64/openpkg does not exist.
I found the directory /tmp/openpkg-20071227-root/kolab/lib/openpkg but 
it does not contain the file rpmt.

What's going wrong? Can anyone help me?

Thanks,
Manuel
