Installation issue

[Net Warrior]

Hi here guy, during the installation process I've get this error,  Am I
missing something?
Do I need to install an extra package? is this a bug?

Generating 00INDEX.rdf for source distribution ...
openpkg:ERROR: No such command "index" found in command path
openpkg:ERROR: (/kolab/libexec/openpkg).
openpkg:ERROR: Set ${OPENPKG_TOOLS_CMDPATH} appropriately.
openpkg:ERROR: Run "/kolab/bin/openpkg --help" for list of valid commands.

There is no index  file under libexec directory.
This is version 2.2.0 installing from source under SLES10

Thanks in advance.
