PORTS_MODULES=x11/nvidia-driver-340 results in [all] Stopped -- signal 22

# cat /etc/src.conf 
PORTS_MODULES=x11/nvidia-driver-340 net/bwn-firmware-kmod
#

on buildkernel I get:

===> Ports module x11/nvidia-driver-340 (all)

I think this used to work with x11/nvidia-driver.

$ pkg info -xo nvidia-driver
nvidia-driver-340-340.76       x11/nvidia-driver-340

Is there anybody else with x11/nvidia-driver-340
using PORTS_MODULES=x11/nvidia-driver-340 in /etc/src.conf?
Or am I missing something simple?

Thanks
