We've just released gnomemicu 0.98.126. I'm attaching an ebuild.. In my opinion (I might be biased, I'm co-maintainer), this is much more stable than 0.98.3 and since Gentoo has gnome2 has the default desktop, it should be unmasked.

One more thing... the requirement has to be on libgnet 1.1.4 .. not 1.1.3 ...
