If you used the package compiz-manager-0.0.1_git071019-11.1.noarch and you wanted to update or deinstall it, you probably have experienced error messages like:
/var/tmp/rpm-tmp.56909: line 8: syntax error near unexpected token `fi'
/var/tmp/rpm-tmp.56909: line 8: `fi'
error: %postun(compiz-manager-0.0.1_git071019-11.1.noarch) scriptlet failed, exit status 2
The trick is, to deinstall this stuff via a root console by executing rpm -e --noscripts compiz-manager - this will remove it from the database and you can install the updated version.
