Dcell on Heroku and `lsb_release -d` causes catastrophic failure

I have forked a copy of the ffi-rzmq gem and added in some Heroku (via bash) compiled zeromq libraries:

https://github.com/jsgoecke/ffi-rzmq/commit/ae88b6bc8f5b6f28017385777068a2c206065b37

But when I try to kick off the process on Heroku I am getting an error from this line:

https://github.com/celluloid/dcell/blob/master/lib/dcell/info_service.rb#L48

Here is the error itself:

This causes a catastrophic failure of the application. Would be great if it gave a warning instead.
