I did "pkg_tarup -a firefox"... it created the following packages:
Xft2-2.1.6nb1.tgz, firefox-1.0.1.tgz, freetype2-2.1.9nb1.tgz,
gtk2+-2.6.4.tgz, jpeg-6bnb3.tgz, libIDL-0.8.5.tgz, png-1.2.8.tgz

but according to
ftp://ftp.netbsd.org/pub/NetBSD/packages/pkgsrc/www/firefox/README.html,
firefox also needs:
glib2>=2.6.1 {perl>=5.0,perl-thread>=5.0} xdg-dirs>=1.1 atk>=1.8.0nb1
glib2>=2.6.3 glib2>=2.6.2 pango>=1.8.0 fontconfig>=2.2.96nb1
expat>=1.95.8nb2 Xrender>=0.8.4nb1 tiff>=3.7.1nb1 xcursor>=1.1.1nb2
Xfixes>=2.0.1nb1 fixesext>=2.0 Xrandr>=1.0.2nb1 
to run... am I missing something?
