is there a reason you didn't build it from the official Go sources?
i only needed to make a couple of tweaks (see the patch below) to
build it.  a couple of things to watch out for:

- make sure you have two different GOBIN's; one for your local Linux
box and the other for making the Plan 9 binaries
- be sure to have the right GOBIN in the first part of your PATH for
your target environment

i use drawterm from the build box and then i can execute Plan 9
binaries produced by 8[gl] from /mnt/term/<whatever>
