Installing VboxLinuxAdditions on CentOS5 (RHEL5 clone) guest fails

[rainbowbuilder]

When I try to install the VboxLinuxAdditions on the CentOS5 beta guest (this is a RHEL 5 clone) I get the following in the install log. Is this a problem that I need to report to CentOS or is this a VirtualBox problem.

Building the shared folder support kernel module.

Fixed in svn, fix will be included in the next release. Problem is that redhat ported back some stuff from 2.6.19 to their 2.6.18 kernel.
