[lxc-users] Question about existing defaults

I followed the instructions and it works, indeed.
I erased first all lxc rpms and the installed the new ones

rpm -qa |grep lxc

However, I hit a problem when starting a container.
lxc-start -d -n dialer-1
lxc-start: symbol lookup error: lxc-start: undefined symbol: lxc_caps_init

This means that the code is left to pull this function from package
that is not there?

Any help would be appreciated, or a patch that would not use this
function. My containers are unbound, only for internal use, so I want
them to use as much resources as needed.
