http://devmanual.gentoo.org/ebuild-writing/functions/src_install/index.html#trivial-installs The 'trivial install' code lacks a lot of obligatory '|| die' statements. I think the issue is quite important as we often tend to refer to devmanual to newbies, and it's really a bad idea to refer to a docs having such serious QA issues.
Created attachment 248454 [details, diff] Patch to fix the issue
Michal, I very much agree with the change that you make, but can not find that there are other functions in devmanual with " || die " missing?
Fixed Thanks Michal
