When I run NodeBB without passanger using reserved port everything is OK. There is problem when Passenger is involved.

My configuration:

Passenger v5.0.30
Node.js v4.7.2
OS: FreeBSD 10.3-STABLE

nodeBB version:
git clone -b v1.x.x https://github.com/NodeBB/NodeBB.git
Configured using ./nodebb Set up for use of MongoDB.

Problem:
After I try to load page I get error page from Passanger and nodeBB is not loading

In errorlog

Substitution of:

to:
var mongoPkg = require.main.require('/home/someuser/domains/nodebb.somesite.net/public_nodejs/node_modules/mongodb/package.json');
Page is loading but does not have full functionality (e.g. I can't post to the forum).

I do not have any problems with running other Node.js apps with use of Passenger. It seems like Node.js modules have some problems with loading full path.
