[gentoo-user] emerge: 'libsandbox.so' from LD_PRELOAD cannot be preloaded

[Grant Edwards]

One of my systems has suddenly started displaying a lot of error
messages any time any package is emerged:

 >>> Emerging (1 of 1) x11-terms/rxvt-unicode-9.18
 * rxvt-unicode-9.18.tar.bz2 SHA256 SHA512 WHIRLPOOL size ;-) ...                               [ ok ]

Googling that error yeielded one suggestion that the sandbox package
was broken and needed to be re-emerged.  I did that, but it didn't help.

I also tried a revdep-rebuild, and it didn't find anything that needed
rebuilding.

According to
http://wiki.gentoo.org/wiki/Knowledge_Base:Object_libsandbox.so_from_LD_PRELOAD_cannot_be_preloaded
that message should never occur except right after a particular
message about SELinux security labels.

Any ideas why this would suddenly start happening?
