Thanks for that bit of information! With the following patch I was able to
get open-vm-tools to successfully compile:

I cannot say if makes these modules work or not, as I don't use them (my
main reason for having open-vm-tools is for vmware-guestd and its ability to
sync the VM's clock to the host), but the port compiles cleanly with this.
Thanks very much!
