Running Suse11sp2 with Xen for various Windows and Suse VMs.

I am trying to run VmPlayer 5 on the Suse Xen server to enable me to run a FreeBSD Application/Appliance.

If I boot the server into plain Suse the VmPlayer application loads and I can run my FreeBSD application with no issues. If I then boot the server into Xen and then try to load the VmPlayer I get the following errors in /tmp/vmware-root/vmware-modconfig-7275.log
Building module with command " /usr/bin/make -j8 -C /tmp/modconfig-1bzOse/vmmon-only auto-build HEADER_DIR=/lib/modules/3.0.13-0.27-xen/build/include CC=/usr/bin/gcc IS_GCC_3=no"
Failed to build vmmon. Failed to execute the build command.

Any help would be great.
