[Kroupware] Suse 8.1-Installproblem : kolab.log contains errors

[testuser]

Hello, maybe you can help : this the content of the kolab.log after
running " sh ./openpkg-1.1.0-1.1.0.src.sh --prefix=/kolab --user=kolab
--group=kolab 2>&1 | tee > kolab.log" 

./openpkg-1.1.0-1.1.0.src.sh: extracting to openpkg-1.1.0-1.1.0.src...
./openpkg-1.1.0-1.1.0.src.sh: line 79: uudecode: command not found
./openpkg-1.1.0-1.1.0.src.sh: line 82: openpkg-1.1.0-1.1.0.src.tar.Z: No
such file or directory
./openpkg-1.1.0-1.1.0.src.sh: extraction done.
./openpkg-1.1.0-1.1.0.src.sh: building for /kolab...
./openpkg.boot: ./openpkg.boot: No such file or directory


There is now a Subdir openpkg-1.1.0-1.1.0.src.
 But there is no "openpkg-1.1.0-1.1.0.ix86-linux2.4-kol.sh"

What went wrong ? 

Thanks for your effort.
