I followed the command line at npmjs.org to install the npm, seems that no error and it's installed correctly.
But when I use it install "jake":

sudo npm install -g jake

A window is poped out with these info:

Chris Rorden's NPM :: April 13 2011 (Debian) CacheMB = 512; Threads used = 8

After I close the window, the error info are printed out in my terminal:

=====================================================
[CRITICAL] os_pager_hide: assertion `OS_IS_PAGER (pager)' failed

(npm:21939): Gtk-CRITICAL **: IA__gtk_widget_hide: assertion `GTK_IS_WIDGET (widget)' failed
[CRITICAL] os_pager_set_parent: assertion `OS_IS_PAGER (pager)' failed
[CRITICAL] os_pager_hide: assertion `OS_IS_PAGER (pager)' failed
=====================================================

if I use "npm config set unsafe-perm true", my installation won't be blocked by those errors and jake is installed.

Is that normal?
