Hi,

My attempt to (belatedly) follow the instructions below has been
hindered by the fact that I don't seem to have the arm assembler 5a on
my i386 plan 9 system.

ls /bin/?c yields lots of compilers

ls /bin/?a yields only 0a and 8a.

Is 5a supposed to be there by default or should I build it from
source? If so how.

Thanks,

James

Thanks,

James
