MSGViewer works, although I haven't used it on Gentoo.
I *think* msgconvert works as I wouldn't have it installed otherwise. I have an ebuild for Email-Outlook-Message but don't remember if I downloaded it from somewhere or hacked it together myself. Hhm, the description is totally wrong, so I'm probably to blame for it ... here's a version with fixed description, and I hope I'm not stepping on anyone's legal toes here wrt copyright. It's goes into /usr/local/portage/dev-perl/Email-Outlook-Message.
