[gentoo-user] Trouble with portage

[econti <contiemilio@alice.it>]

Hi all,
to-day I am having some trouble to update my system.
Well, 'emerge --sync' and I received a message telling me a new version 
of portage is available and I should update it immediately. But, before 
upgrading it I ran 'emerge -NDpvu world'. Here is the output:

 >localhost ~ # emerge -NDpvu world

As you can see the first "package" to upgrade is portage. Then 'emerge 
portage' and after 'emerge -NDpvu world' and here the new output:

 >localhost ~ # emerge -NDpvu world

Following what the last message said I added 
'>=www-client/mozilla-firefox-2.0.0.0' line in 
/etc/portage/package.mask. Then I ran 'emerge -NDpvu world' one more. 
And here is the output

 >localhost ~ # emerge -NDpvu world

 >These are the packages that would be merged, in order:

 >!!! All ebuilds that could satisfy "=www-client/mozilla-firefox-2*"

 >(dependency required by "gnome-extra/yelp-2.22.1-r2" [ebuild])
 >(dependency required by "app-doc/gnucash-docs-2.2.0" [installed])
 >(dependency required by "app-office/gnucash-2.2.7" [installed])
 >(dependency required by "world" [argument])

The list of packages to upgrade disappeared. Coul anyone tell me what I 
am doing wrong?

Thanks
