While emerging xearth-1.1, I get the following error: doman: 'xearth.man' is probably not a man page. The result of this, is the xearth package not having a man page.
doman looks at the file ending to determine where to put the manpage ... in other words if it isnt of the format name.[1-9] then doman has no idea where to put it http://cvs.gentoo.org/cgi-bin/viewcvs.cgi/gentoo-x86/app-misc/xearth/xearth-1.1.ebuild.diff?r1=1.5&r2=1.6
