I've been having a problem with vmware ever since I updated my operating system. I get the following error:

Unable to build kernel module.

See log file /tmp/vmware-root/setup-28093.log for details.
before I even try to load a virtual machine.

This is the contents of the log file:

I'm not sure what information you need about my setup to help me out, but I do have Ubuntu 10.04, (yes I know, Ubuntu ), and the software is just vmware player.
