Copying the current 0.16 ebuild to 0.17 caused no problems here.
Emerged perfectly here too. It's a dependency required to emerge monodevelop. See bug: http://bugs.gentoo.org/show_bug.cgi?id=43816
No problems here either when renaming to 0.17.
In fact the severity of this bug is BLOCKER of monodevelop, not an enhancement, but anyway.
I also emerged it with a simple number bump and have used it with no problems. It's necessary for muine-0.5.0.
