Yes, C tests start ZK server and are tested against it. There are a few that
use mocked server, but that's a legacy code I think.

Re the problem itself:
1) check ZK server logs at build/tmp/ , maybe log contains some info about
why the server fails to start
2) are you absolutely sure you have no zk processes running? I usually do
"ps -ef | grep zoo" and it always helps
