Hi

i get the error:

{
!!! Multiple package instances within a single package slot have been
pulled
!!! into the dependency graph, resulting in a slot conflict:

media-libs/libpng:0

  ('ebuild', '/', 'media-libs/libpng-1.4.3', 'merge') pulled in by
    >=media-libs/libpng-1.2.43-r2:0 required by ('ebuild', '/',
    >'x11-libs/cairo-1.8.10', 'merge')
    >=media-libs/libpng-1.4 required by ('ebuild', '/',
    >'x11-libs/gtk+-2.20.1-r1', 'merge')
    (and 27 more)
}

And i wonder that it seems not to be possible to install both libs
(libpng-1.2.43-r2:0, libpng-1.4) in the same time. Linux is actually 
able to manage this by the lib-version and links.

Did i have overseen any gentoo switch that makes is possible? Or is
there any other option?

Regards
