I'm very (very) new to node.js, and also fairly green when it comes to server side configuration and coding. (I have a long history of client-side programming, most recently with Adobe Flex and ActionScript.)
Anyhow, I asked Rackspace (who manages a Linux server for me) to install node.js and node-postgres.
From the comments in the ticket, that installation went like this:
node.js
Running Transaction
Installing : nodejs-stable-release [1/1]
Installed: nodejs-stable-release.noarch 0:5-3
Complete!
and node-postgres

A little “Hello world” node.js example works fine (hooray!), but a simple Postgres example fails on the require('pg') statement, saying that the module cannot be found. I've looked on the server and can't find a pg.js file anywhere.
Any clue as to why the node-postgres build failed?
ls -la /usr/src/node_modules/pgvar pg = require('/usr/src/node_modules/pg');
