Check broctl-config.sh. I ran into this error when I didn't have the
"time" command at the time of bro install. I had done a CentOS minimal
install, and /usr/bin/time was not installed.
Once I installed the time*.rpm, and edited broctl-config.sh to provide
the correct path to the executable, all was well. Example:
time="nice: which:: No such file or directory"
I'd check look for that text in the broctl-config.sh file.
