[gentoo-user] Problem with Portage profile override

Hi!

I do have a problem using /etc/portage/profile/package.provided. At
first I added some other packages to this file and got the expected
functionality. Then I added sys-apps/busybox-1.16 to package.provided.
It works and portage detects the entry on an emerge, but it prints a big
fat warning, that busybox has been excluded and suggests deleting from
worlds file or removing from the package.provided file. But busybox
isn't in the worlds file. And removing it from the package.provided
files leeds to emerge trying to install busybox 1.15.3 which conflicts
with my manual installation of busybox 1.16.0 (or daily snapshot).

How is it possible to disable this warning message from emerge, because
it's half a screen full of text on every merge and scrolls off a lot of
other wanted information from the screen?

If any additional Information required please feel free to ask. I'm new
to gentoo and portage but otherwise a C programmer and more or less an
linux expert.

Thx for your help.
