When emerge -j8 .... (a very cool feature, btw) stops because a package failed to build, a following emerge -j8 --resume --skipfirst claims that there isn't anything to do anymore, which is not true. Reproducible: Always
1) Please post the full output of both commands in sequence. 2) Post your `emerge --info' too.
I might be wrong but this bug looks like a duplicate of bug #247106
Why are you using --resume instead of --keep-going?
