Using FEATURES=-sandbox works. Subsequent re-emerging works. Not sure about intermediate versions, since they're all masked. Steps to reproduce: 1. emerge -1 =sys-apps/sandbox-1.2.18.1-r2 2. ebuild /usr/portage/sys-apps/sandbox/sandbox-1.6-r2.ebuild test FEATURES="distlocks fixpackages parallel-fetch protect-owned sandbox sfperms strict test unmerge-orphans userfetch"

<sandbox-1.3 has known problems with recursive testing. not much i can do about it.
Adding a note in the failure message would help. It currently says * If configure failed with a 'cannot run C compiled programs' error, try this: * FEATURES=-sandbox emerge sandbox configure obviously didn't fail, but FEATURES=-sandbox still helped.
If "FEATURES=-sandbox" is insufficient, you may be using usersandbox and need to drop that as well. That worked for me: FEATURES="-sandbox -usersandbox" emerge sandbox
