[gentoo-user] Conflicting version...but the version scheme is confusing...

[tuxic]

Hi,

I got this printed onto my console after updateing:

  (media-gfx/imagemagick-7.0.9.5:0/7.0.9::gentoo, ebuild scheduled for merge) 
conflicts with
    <media-gfx/imagemagick-7:=[cxx] required by 
(media-gfx/inkscape-1.0_beta1:0/0::gentoo, ebuild scheduled for merge)

What does "media-gfx/imagemagick-7:=[cxx]" indicate for a version ?

Cheers!
