My best guess at what to do is to install some kind of pipe work under
the liner, to allow the gas out before it collects and becomes a
nuisance. Any suggestions?

Never heard of a problem like this, but my first though is to make a
hole at an angle to the trouble spot by shooting a small diameter pipe
to the spot where gas collects.

(Shoot a pipe) Hook up a water hose to a pvc pipe, turn the water on and
push it into the ground as the water washes out a hole ahead of the
pipe.
