Fabric doesn't execute sudo through full login shell and it looks to me like
the /opt/csw/bin directory may be added to PATH by some ksh startup script
(which it doesn't execute when non-interactive/non-login).
To confirm run (not via Fabric):
ssh queue.likestream.net 'which sudo'
If I'm right this will fail to find sudo as well.
Fabric does allow customizing the location of sudo (sudo_prefix) but only in
>= 1.0a, I don't think there are any workarounds you can use in 0.9 apart from
run('sudo ...').
