fluxbox-0.9.15.ebuild contains the following two ewarn lines among a lot of einfo: ewarn "Note that menumaker and similar utilities do *not* support" ewarn "this out of the box." As I have PORTAGE_ELOG_CLASSES="warn error log" in my make.conf, I got an email containing only these lines, which is a bit out of context. It would be nice to have the sentence modified to give a hint what this is all about, or make it just an einfo instead.
Well, so set ELOG so that you get einfo as well to get the context if you need it.
comment #1: This will not help much, because ELOG destroys context as well. The ewarn will be written before all einfo lines. IMHO, the severity (warn, info, error) should never be changed in one context.
Fixed in 0.9.15.1-r1, and 0.9.14-r2 and in 1.0rc
