sci-libs/nlopt has an automagic dependency on Matlab. When the configure script detects Matlab, it attempts to start it in order to get information from it. Matlab requires R/W access to files outside the sandbox, causing violation. Workaround: emerge with EXTRA_ECONF='--without-matlab' Gentoo could either decide to not support Matlab and disable the automagic dependency, or provide a sandbox exception and an einfo notice to rebuild sci-libs/nlopt when (un)installing Matlab. I am in favor of the first option since automatically running a massive proprietary package outside a sandbox doesn't sound very wise. Unless /dev/ptmx (see sandbox log below) is really the only thing accessed.
