Hi Gerion

I believe that what you are looking for are the options starting with
--autounmask, which affect the initial analysis of the build tree,
which is the source of the complaints about missing keywords or USE
flags.
The --keep-going option does a great job at continuing to build other
packages when one build fails.

There are a bunch of them so I don't know how much you'd like to use
but it seems tailored to go forward in almost any situation !
They are well described in "man emerge"
--autounmask [ y | n ]
--autounmask-backtrack < y | n >
--autounmask-continue [ y | n ]
--autounmask-only [ y | n ]
--autounmask-unrestricted-atoms [ y | n ]
--autounmask-keep-keywords [ y | n ]
--autounmask-keep-masks [ y | n ]
--autounmask-license < y | n >
--autounmask-use < y | n >
--autounmask-write [ y | n ]

Adding --backtrack=COUNT with COUNT > 10 (the default value) may push
Portage to look forward a bit more.

However, as I don't use them, I don't know what stability you could
expect from your system after activating any or all of them.
