Thanks to help from Mark Millard poudriere successfully finiished
a build of x11-wm/lxqt on a Pi4. The build command used was 
poudriere testport -j main x11-wm/lxqt

A collection of packages turned up in:

The pkg man page seems to suggest that: 
pkg -r /usr/local/poudriere/data/packages/main-default/.latest/All install
would install all of the new packages. Am I reading correctly? 

Is it possible to try out the lxqt package without altering the
existing ports installed using make in the ports tree?

Thanks for reading, and especially to Mark!
