Sorry I'm not currently able to check this out, but I recall that gnetlist
has (in the past, and possibly currently), not worked properly in the case
where only IO symbols with net=....:1 attributes (but no actual components).

My recollection is not that clear, but try adding a dummy component
(perhaps a resistor), with one pin connected on your schematic where you
join PGND and your IO sym.  Don't need to give it a footprint (but you will
probably get complaints from pcb about the missing component).

If this makes the connection appear in pcb, let us know - and I'll see if
anyone working on the gEDA side of things has any ideas for a fix, or
better work around.

I have an idea that I've made some boards with netlists that featured
Rdummy1 Rdummy2 etc.... and I think I was working around the same issue you
describe.
