out of curiosity...

[blunted]

ebuilds sometimes output info about what needs to be done to get the package in question to work when compiling is complete... is there anyway to check them all after doing, say, emerge -u world?

I know I've seen a thread on this b4. Can't find it right now though. U could redirect the output to a file and parse that file to get the info.
[edit]found the thread. https://forums.gentoo.org/viewtopic.php?t=10883

Locked in favor of the thread data_the_android pointed out.
