questions about Xfce, gtk ans gentoo

[Maximilian Schleiss]

Hi all,
I am using Xfce on a gentoo distro on a toshiba laptop. The bugfix just 
came out in the portage tree, it is still masked but I have a question 
about installing it.
Should I use the Xfce4 base ebuild or is it better to install the 
packages one by one?
The second question I have regards GTK+. I have version 2.6.2 in Slot 2 
and 1.2.10-r11 in Slot 1!?! Is this right?
Have a nice day in sunny europe.
Maximilian
