Hi all!

Something a bit strange has happened to me when I tried to emerge Gnome. It asked me to add a USE flag!
Code:
# emerge -p gnome

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

Calculating dependencies... done!

emerge: there are no ebuilds built with USE flags to satisfy
">=gnome-base/gvfs-1.4.3[gdu]".
!!! One of the following packages is required to complete your request:
- gnome-base/gvfs-1.4.3-r1 (Change USE: +gdu)
(dependency required by "gnome-base/gnome-2.28.2" [ebuild])
(dependency required by "gnome" [argument])


I couldn't find the gdu flag in the list, but I added it anyway. Then I tried again, and it requested me a different USE flag... This continued on and on until I added gdu extras device-mapper policykit sqlite consolekit and cairo. Afterwards, it let me emerge it.

My question is, is this a safe procedure? It's the first time I do this.

Thanks in advance for your replies.

It's in the list:
Code:
~ # euse -i gdu
global use flags (searching: gdu)
************************************************************
no matching entries found

local use flags (searching: gdu)
************************************************************
[-    ] gdu (gnome-base/gvfs):
Enable sys-apps/gnome-disk-utility integration
euse is part of app-portage/gentoolkit, by the way. I highly recommend emerging it if you haven't already.

For the rest, yes, it's safe, and pretty normal. Some package simple require some optional (and USE flag controlled) features of other packages. Portage knows this and manages it for you.

Since USE flags can affect more than one package, you can limit their effect by making entries in /etc/portage/package.use/. However, if you're installing Gnome, you might want to change to the default/linux/x86/10.0/desktop/gnome profile, which sets a reasonable set of USE flags for a Gnome installation.

Thank you John. I'll go for it then!

I didn't know about euse, there are still tools you never heard of!
