Hi James,

sorry for the delay...I was not at home this weekend.

quemu is offered via emerge...will try that first. By the way:
I think the CPU on my Arietta board is a 32 bit thingy.You wrote about
64 bit thumb code...executed by a cluster of 32 bit ARM CPUs...I have
one Arietta board...or...what did I get confused here totally
<scratching my head... ;) >


Best regards,
Meino
