So far I've been able to (re)install Blender, octave and scilab. 'make 
install clean' gcalctool however, gives:

<output omitted>
configure: error: Package requirements ( glib-2.0 >= 2.8.0   gobject-2.0

'less distinfo' for glib2 gives:

$NetBSD: distinfo,v 1.61 2006/04/08 21:23:24 wiz Exp $

Any advise on what to do? I thought pkgsrc was meant to automatically 
build dependancies as well?
