problem after upgrading to 'virtualbox-ose-4.3.22'

[Raul]

After upgrading emulators/virtualbox-ose up to 4.3.22
using portmaster, without QT4 and X11 (headless box), I get:

[....]
#/usr/local/etc/rc.d/vboxheadless start XXX
Starting Virtual Machines:
                   XXX Unknown machine
[....]

and if I try VBoxManage:

[....]
% VBoxManage list vms
Could not find VirtualBox installation. Please reinstall.
[....]

Anyone seeing the same behaviour.

Thanks in advance.
