Looks like it is an issue with mdns module itself? I tried to install mdns globally and got the same error.

$ sudo npm install mdns -g

Ok got it. It seem mdns requires libavahi-compat-libdnssd-dev to be install first. For ubuntu 14.04 I ran sudo apt-get install libavahi-compat-libdnssd-dev and uninstalled proccess-boss then re installed and now it works.

This should be an optional dependency. I mean, it is in the package.json but boss should handle it being missing at runtime.

I guess the annoying thing is that (as you found out) if you install boss without avahi installed, then install avahi, you have reinstall boss as it compiles the native module at install time. Not sure if we can do anything about that.

Reopening as a reminder to self to handle the missing component more gracefully.

This should now not prevent the web interface from starting up in boss > 2.5.3
