Either as a mistake or otherwise, eroaster-2.1.0.ebuild was never built to actually suit Eroaster. For instance, the original ebuild was pretty much a standard configure/make/make install, but anyone who has compiled Eroaster know it doesn't respect DESTDIR. Attatched is a working ebuild for eroaster-2.1.0.
Created attachment 2227 [details] ebuild for eroaster-2.1.0 Corrected ebuild for eroaster-2.1.0
Please also look at bug 4807 for an <a href="http://bugs.gentoo.org/show_bug.cgi?id=4807#c2">earlier comment</a> I made about the eroaster ebuild in general.
Forget this bug. Current eroaster-2.1.0.ebuild in portage is proper and better then mine. blah
