I have no clue.

I never have seen this?  Maybe the permssions on the 'ipcs' executable
are wrong.  When I bought my 3b1 the "ipc's" weren't being loaded upon
bootting.  Try '/etc/lddrv/lddrv -s' , I think this shows the drivers
that are loaded - I don't think this is your problem though :).

I got it to compile and run.  I set the max player limit to 3 mainly
because I'll never have more than 3 users on my system anyway.  I
haven't tried playing with two players yet.  I did notice that one
player was SLOW.  I was thinking of slowing down the "clock daemon".
Let me know what happens.
