Installation of Kolab 2.2-rc3

[Christian Tardif]

I'm trying to install Kolab-2.2-rc3 under Mandriva 2008.1. The first 
part of the installation (openpkg) seems to work correctly, but after, 
it ends with this error:

/kolab/lib/openpkg/openpkg: line 299: exec: shtool:path:Error:: not found

I've googled to find out how to fix it, but I haven't find much to help. 
Someone's, here, knows what it is and how to fix it?

Thanks,
