looks like you are using 'raw' kernel headers here
(which unfortunately will not work, not just for util-vserver
but also for all other software including linux/* stuff)

the glibc 'usually' provides heavily cleaned up kernel headers
which do work outside the kernel (for userspace apps)

so, doing ln -s /usr/src/linux/include/linux /usr/include/linux
is a very bad idea unless you know what you are doing ...

HTH,
