This was discovered during work on the XD2GEN2 project. While Ximian has made no changes to this package, they do ship with the latest version (0.37) which is not in the portage tree yet. As far as I can tell, the ebuild doesn't require any modifications other than updating the SRC_URI.
if you're gonne add more ebuilds/request over time, please _do_ check the ebuilds. there were a lot of improvements possible in this one. 0.37 now in ~ , see how it works (removed some unaccounted for deps, not sure how thats gonna work on a clean sys).
