I would need to read into how to do this best on OpenBSD.

Using :
"LD_PRELOAD=/usr/lib/ ./LCDd -c LCDd.conf"

Preloading the "" makes the server connect to the display.
I can then run a lcdproc client like this :
"./lcdproc -s localhost -f -p 13666 P I"

The LCD then displays the screens I expected "P,I"
So this work around makes the display work.

However I am unsure what a more permanent fix would be at this point.

Thanks for your help
