Missing dependency on Ruby 2.3

[Rene Horn]

System info:

    Description: Ubuntu 18.10
    Release: 18.10

    bro:
      Installed: 2.5.4-1build1
      Candidate: 2.5.4-1build1
      Version table:
     *** 2.5.4-1build1 500
            500 http://us.archive.ubuntu.com/ubuntu cosmic/universe amd64 Packages
            100 /var/lib/dpkg/status

On trying to run bro, all I get is:

    $ bro lsof
    Failed to execute process '/usr/local/bin/bro'. Reason:
    The file '/usr/local/bin/bro' specified the interpreter '/usr/bin/ruby2.3', which is not an executable command.

Expected:
    # List all web processes
    lsof -i :80

Thanks for taking your time to report this issue and help making Ubuntu better.

I tried to reproduce this issue by running bro on Ubuntu 18.10 but I didn't see any error messages. Looking closer at your output, it is talking about '/usr/local/bin/bro' which doesn't seem to be part of the Ubuntu package (https://packages.ubuntu.com/cosmic/bro). Could this be separate bro binary either installed locally or from third-party?
