I'm currently trying to get Planeshift to work on the amd64
architecture. However, I'm running into errors when compiling ode-0.5 on
an Athlon64 box.  I have submitted a bug report in Gentoo bugzilla here:
http://bugs.gentoo.org/show_bug.cgi?id=52919

Could someone offer some insight into what may be causing these compile
problems?  I could probably find you a machine to SSH into to test fixes.
