Hi Peter,

I'm helping Paul with this. Sadly, I'm not much of an npm expert

I believe that this refers to native code depending on another native
library (e.g. libfoo). In this case, a package for libfoo would have to
be available and added to DEPENDS. This is not applicable for modern-
syslog. Paul - correct me if I've got this wrong.

Good idea, but we need to balance the complexity of adding another tool
vs. figuring this out with npm.

Back to the problem. I have re-created the statsd build failure, and
agree with your diagnosis, but don't have am immediate solution.  

I have opened a bug #10760, and added you to CC list. Let's use this
bug to communicate from hereon.
